...Namjoon's P.O.V...

I was searching for movies to watch when my best friend came in and stood at the door watching me at the same time, my phone rang. I was a little nervous when I saw it was Nina.

I waved him and padded after him as he headed straight to the kitchen with his latest beer offerings. That got a smile out of me. At least when I was done with this call, I could have a good beer and some company.

Nina: Hey, Joon

Namjoon: Hi, Nina. How's it going?

Nina: Great. But actually, I have something to tell you.

Namjoon: What's the matter?

Nina: My team has secured funding for our latest project, so I'll stay in Southeast Asia for the summer.

Namjoon: Wow, that's awesome.

Nina: Yeah, you know I've been waiting for this for a long time. But I can't take Richie with me. So, he needs to spend this summer with you.

Namjoon: Well...

Nina: Namjoon, you promised you'd be supportive.

She didn't sound whiny; she sounded firm. Determined. Excited. All the traits that had made me fall in love with her in the first place. Nina was the kind of woman who knew what she wanted out of her career. Out of her whole life.

Namjoon: You have to admit that it's pretty last-minute.

Nina: I would've given you more notice if I could've. You know that I would've, Namjoon. But as it is, we've just heard back you know how it goes. This is a big deal for my career.

Namjoon: I know, I know. It meant that for the entire summer, I would have sole custody of our son, Kang-dae.

Namjoon: Okay. Don't worry. I'm excited to have Kang-dae her for this summer. We're going to have fun.

Nina: Really? That's so great, Joon!

Namjoon: Of course. I'm Kang-dae's dad; this is what I'm supposed to do. But I have my tenure review in the fall, and that means I'm going to be working hard all summer on my article. I'll spend time with him, though. Don't worry.

Nina: If it's too much for you, he could probably stay with my mom.

Nina offered but that sent another stab of guilt through me. I didn't want Kang-dae to think that I didn't love him. That my career was more important to me than him. Nor did I really want him to stay with Nina's mother for the whole summer. I knew what the woman thought of me and of the way that Nina and I had chosen to raise Kang-dae. I could only imagine what might happen if Kang-dae went to stay with her.

Namjoon: I'm excited to have him.

Nina: He's excited, too.

Nina said; but, there was a certain reluctance in her voice, as though she wasn't sure that she really wanted to tell me that.

Nina: Look, there isn't any pressure, okay. Just don't make him like a burden.

Namjoon: Nina, I'll never do that!

Nina: I know. Anyway, I'll let you know when I've booked my flights so that you know exactly when I'm leaving.

Namjoon: Do that.

Nina: Okay. Talk to you later, then.

Namjoon: Sure, bye-bye.

Jin, my best friend, immediately pressed a beer into my empty hand and led the way out to the back patio. We dropped into the chairs. For a moment, we were both silent.

Jin: So... How's it going?

I sighed and shrugged one shoulder.

Namjoon: I'm feeling a little overwhelmed. I'm happy for Nina, don't get me wrong. But I have so much other sh*t going on in my professional life at the moment that I just can't help but feel like I'm drowning.

Jin: The new article not going so well?

Namjoon: Barely off the ground. It's been hard with the new classes that I'm teaching this semester and in the fall. I've been up to my eyeballs in curriculum planning. The spring semester is nearly over, though, and I've already submitted all the preliminary paper work for the fall courses. So I was finally starting to feel like the point where I could really focus on the paper and get a lot of work done.

Jin: Yeah, ouch.

Jin said, watching as I took a long swig of my beer. I made a face and peered at the label.

Namjoon: Ginger beer?

Jin: New dude is courting me. He thinks he can somehow get away with marketing it as healthy because there's so much ginger content.

Namjoon: Maybe it would be healthier if you drank less.

Jin: Clearly, you're doing an amazing job of taking care of yourself. Let alone Kang-dae.

I glared at him and he laughed.

Jin: Joking, man.

Namjoon: It's just different. Normally, Kang-dae is only here for four days at a stretch at most. It's nice that Nina and I are still in the same city. It works... It means that if I have to order takeout for us sometimes because I'm swamped with work and possibly anything else.... Well, it's not the end of the world though.

Jin: But you can't live like that for the whole summer.

Namjoon: Exactly. Plus if I'm going to have all this time with Kang-date, I'd like to actually enjoy some of it. You know, get a chance to hang out with him. But the only way that I'm going to be able to do that is if I can get some serious work done on the days when I'm really working. And I can't do that if Kang-date is underfoot.

Jin: Then get a baby sitter. I'm sure if you pay a little extra, you could even get someone who'd be willing to grab groceries for you.

Namjoon: The advice is actually wonderful. It'd be perfect if we had a live-in nanny. But it'd be hard to find a suitable person.

Jin: I have a suggestion, actually. You remember my younger sister, right? Y/n?

Namjoon: Uh, yeah?

She'd always seemed like a nice girl, although I didn't think that I'd seen her since high school. She was kind of quiet. Bookish. Was she really the right fit for Kang-dae?

Jin: She's starting a master's program in the fall, in child psychology. She's been working at the on-campus centre, but they want to give her position to another undergraduate. Anyway she's really good with kids and she's more outgoing than she use to be, too.

Could I really afford to be picky, anyway? If Y/n doesn't connect with Kang-dae, that'd be probably be a recipe fore disaster. But then, what was I supposed to do? I couldn't just fail my tenure review because I was busy picking up the slack. I needed this. Besides,if Jin was vouching for her, it had to be because he really thought this was a good idea. I knew that Jin loved his sister, but we were best friends. He wouldn't want to put me in an awkward position.

Namjoon: Are you sure that she might be interested? Working as a nanny is a lot different than working at a child daycare centre.

Jin: She's looking for anything that she can find for the summer that's going to pay her decently. She can put off paying student loans as long as she stays in school. But the tuition for her grad program sounds brutal, and she currently has nothing coming in until her TAship starts in the fall. Anyway, she loves the beach, and as close as you live to it... I bet if you give her one day off a week, she'll be over the moon.

I trusted Jin.

Namjoon: Will you check with her?

Jin: Already sending her a text. I'll let you know as soon as I hear from her.

Namjoon: Thanks. I said, feeling a sudden wave of relief flood through me. Maybe things weren't going to be so bad after all. Maybe I was finally going to get my life under control.

Jin: So, what are we ordering for dinner tonight anyway? I assume there's nothing in the house. You should've told me to bring something over.

Namjoon: Beer is what I really need. I found this new place, though. Peruvian. They deliver. I figured out since it's our biweekly poker night, it'd go well with the cigars.

Jin: Now that's thinking ahead.

It was our biweekly poker night, and tonight, I truly was feeling lucky. I just had to hope that it'd last.

...PARK Y/N'S POV...

I rolled my eyes when I finally found Jin seated towards the back of the "pub".

Y/N: Seriously? Slaters.

I groaned as I slid into the booth across from him.

Jin: You owe me one. You made me go to that terrible Korean food place last time. What was it called again? Raging Sung's?

Y/N: Yeah, I guess you're right.

Jin: I had food poisoning for like, two weeks after that one. I guess we know why Sung was raging.

Y/N: Yeah...

I topped digging at him.

Jin: You do remember that Namjoon has a kid now, right?

Y/N: He's still your best friend isn't he? Doesn't best friend duty mean anything?

Jin: Best friend duty has nothing on sisterly duty. So, come on, what should we order? I'm thinking of just a tray of appetizers to share.

Y/N: Fine , but you'd better buy me a drink first. And have them make it strong.

Jin: Deal.

He eventually flagged down the waitress and ordered for both of us. Then, he turned back to me, putting both hands flat on the table.

Jin: So about Namjoon.

Y/N: What's Up? Is he getting married again?

Jin: No, thank God.

Y/N: What do you mean?

Jin: I meant that he doesn't have much time now. His tenure review is coming up in the fall, and he's got his son Kang-dae for the whole summer, too.

Y/N: Where's Nina?

I knew how custody over a child works. If Christian had their son for the entire summer, Nina must have given up the privilege.

Jin: She's going to be in Southeast Asia, doing some archaeological dig. She dropped all of this on Christian super last minute, but it's not like he can really argue with it. But the guy can barely keep himself alive as it is, having his son half of the week. So honestly I don't know how he's going to get through the summer.

Y/N: He's a professor, though, isn't he? Even if he's teaching a summer course, he can't really be working all that much.

Jin: His tenure review is coming up. He's working on an article, something about brutal customs in far-flung places. I don't know.

Y/N: Fair enough. So, why are you telling me all this?

Jin: I was thinking that maybe he could use a nanny for the summer.

Y/N: Is this just another sisterly duty?

Jin: Of course not! I just know that you're looking for a job for the summer. And I figured that one where you got to work with kids was better than the one where you had to, I don't know, wait tables.

Y/N: You're right about that. But Jin, I doubt that some glorified babysitting job is going to pay well enough. Sorry, but that's just the way it is. I have to pay grad school tuition in the fall, plus I'll be so busy with the TAship and everything else that I doubt I'll have much time to actually work. I need to save up a lot this summer.

Jin: I know that. Look I wouldn't have suggested this if I didn't think it was a good idea for you. I know you need to make a little cash. Namjoon is more than willing to make it worth you while. Especially since he's looking for a live-in nanny. So that he doesn't have to worry about his writing hours being interrupted when he's "in the groove" or however he put it.

Y/N: Fair enough.

Jin turned his phone around to show me something, and my eyes nearly bugged out of my skull.

Jin: Think that would be a fair weekly rate?

Y/N: Are you sh*tting (kidding) me?

Jin: Not only that, but you'd only be, like, a ten minute walk from Revere Beach. Plus of course, you'd just have to walk downstairs to get to work. A bit better than your current commute, isn't it?

I made a face. As much I loved my roommate and our cramped but cozy apartment in Newton Corner... I had to admit that it was a pain in the butt to get anywhere without driving. And the trouble with driving in Boston was a nightmare at the best of times.

Jin: So, what do you think? He doesn't know exactly when Nina is leaving yet, but he thinks its probably going to be sometime within next week. So, basically, he'd want you start as soon as possible.

Y/N: Yeah, sure, I'm interested. Go ahead give him my number.

Jin: Already have. I knew you couldn't resist a beach-side spot for the summer.

I rolled my eyes, but I didn't protest.

Now in her apartment....

That evening, I headed home to my apartment. I flopped down on the couch next to Alison, my roommate.

Y/N: I have some bad news...

Y/N'S POV

Y/N: Uh-oh

Allison: Something with Jin? Is he alright?

Y/N: He's fine. But he's (he has) talked me into taking a nannying job with his friend Namjoon

Allison: You're not telling me that you're moving out, are you?

Y/N: Of course not. Just that I won't be around as much as I'd (I had) planned this summer. But starting in the fall, I'll be right back to bothering you as normal. The commute sucks from here, but apparently, he lives within walking distance of Revere Beach, so it'd (it would) be even worse from there. Besides, he only has sole custody of his son for the summer because his ex is in Asia or something for work.

Allison: Well it sucks that we won't be able to hang out as much, but I get it. A nannying position would be great for you. You're so good with kids. It would be a waste of your skills to work in a coffee shop or something.

Y/N: *I grinned* Yeah, honestly, I feel like this is the best thing that could happen to me this summer.

Allison: You'd better come back from time to time, though. I don't want you to miss all the parties and girls' nights.

Y/N: Of course I won't.

Allison: Well, if we don't have much time, we'd better make good use of it. Let's order some food and watch trashy movies and stay up until dawn.

Y/N: Sounds like a plan. Jin brought me to some place so that he could do some business deal, and I barely touched the food there.

Allison: Ugh, I'm not surprised. So, Mexican? Pizza? Thai?

Y/N: All of the above? Even though I'm trying to watch my budget, I guess I can splurge a little for once. I'm going to be saving up for the next few months anyway.

Allison: I like the way you think.

Allison said, grinning.

........

NAMJOON'S POV

I automatically checked my watch as I answered the door on Sunday. She was perfectly on time. I appreciated that, and I intended to let her know.

When I opened the door, though, all thoughts flew right out of my mind. The woman standing there had a pretty, heart-shaped face, and she was thin with soft feminine curves. The vision of loveliness didn't seem to notice my dumbstruck expression.

Y/N: Hey, I'm Y/N.

I slowly shook her hand and then coughed slightly.

Namjoon: We've met before.

The years had made her hotter than I could've ever imagined. I'd really never thought of her as an adult. The years had matured her. I'd seen her graduate from high school, but it'd been difficult to ever really think of her as an adult. Suddenly it wasn't so difficult anymore. The evidence was right in front of my face. I forced myself to stop that train of thought right there.

NJ: *She's Jin's sister. He'll kill me if he finds out I'm thinking of her in a... sexual way. Not that I'm thinking of her in a sexual way. I'm just appreciating the way she looks. That's all.*

Of course, the fact that she'd be sleeping under my roof most nights of the week didn't escape me. Neither did the irony of the situation. I was hiring a nanny so that I could work distraction free. And the nanny herself might be the biggest distraction I'd ever seen.

Y/N raised an eyebrow at me, and I suddenly realized that she was still standing on the door step with her bags.

Y/N: Aren't you going to let me in?

I cleared my throat awkwardly and stepped back to let her into the front hall.

NJ: Sorry.

Y/N: Don't worry about it.

NJ: Oh hell, I'm in for it. Here's the living room, and then the kitchen is through here.

We headed further into the house and up the stairs.

NJ: This is Kang-dae's room. He's still with Nina and won't be arriving until tomorrow.

Y/N: I'm looking forward to meeting him. He's interested in cars, I can see.

NJ: You're probably going to have to play racetrack with him all summer.

Y/N: That's fine. Seriously, Namjoon. I like kids. They're fun. They're handful sometimes but I like working with them. Don't worry.

NJ: I know. Anyway, like I said he, won't be here until tomorrow. So you've got tonight to settle in a little before you go on duty. I'll show you your room, and then you can get settled in.

Y/N: Sure.

NJ: For some reason I feel surprisingly nervous. But about what? That if she doesn't like it, she'll be out of there? I can already tell she wants to be here. She'll stay until I send her away. Would I have to send her away? What if things become too much?

Y/N: It's beautiful.

The room had a fresh feeling, but I'd been worried it'd seem a tad too impersonal. I hadn't spent much time decorating the guest room.

NJ: I was planning to put some plants in here. But I didn't want to get a bunch that you were going to have to take care of and make more work for you. *Oh... now I was the one who was babbling*

Y/N: Maybe Kang-dae can help me pick out some plants one afternoon. It'd get us out of the house.

NJ: Sounds nice. Oh, and here's a key. I guess I should leave you to get settled.

Our fingers brushed as I passed her the key. I fought not to react as lightning bolts jolted through my whole body. What was it about her that had made me so interested? I barely even knew her, and I didn't want to think that I was one of those people to whom looks were the only thing that mattered. I didn't want to think I was the kind of person who could think of f*king his best friend's younger sister. Because that was what it was really about, wasn't it?

Y/N: Sounds good. How about I'll make dinner in about an hour, and we can eat together?

NJ: Sure. *I said surprised to hear her volunteer*

I backed out of the room before I could say anything stupid.

NJ: *What the hell have I gotten my self into?

............

Y/N'S POV

I had to admit that I was pretty surprised when I first saw Namjoon. His hair was swept casually out of his piercing hazel eyes. And there was something about the way he kept looking at me, It had me tongue tied. I tried not to make too much of a fool out of myself. Still, I didn't want him to think that I was assessing his parenting skills or anything. I wasn't there to judge him. I was there to do a job.

Y/N: *Why does it suddenly seem like it'll be difficult to do so? Why does it suddenly seem like it's going to be impossible for me to keep my hands off him?*

I left my bags in a pile on the floor and flopped down on the bed, taking a moment to just breathe. I liked the room, though. And if I could just manage not to be a total spaz, I was pretty sure that this would be good for both of us.

Y/N: *Of course, I have to be careful to keep things strictly professional. I can only imagine what Jin would do to me if he found that I had a crush on his best friend. No, Jin would never approve, even if it was just some sort of friends-with-benefits setup. He'd never want to think of me, his younger sister, as having such a relationship. He wouldn't want to think of me having sex at all. He still treats me like I'm a little kid sometimes. But I'm not a kid anymore. I wonder if Namjoon still thinks of me as one. But no, the look on his face... When he opened the front door he has shown me clearly that he doesn't think of me as a kid anymore.*

*I grinned up at the ceiling. Namjoon had definitely been interested in me. Not that I could take advantage of that fact, but it was nice to know. He was damned good-looking himself, so for him to think that I was attractive? Well... Now, though, I was even more worried about this whole situation. What if I did something foolish, like making a move on him? I had no doubt that no matter how interested he might be, he'd still rebuff any advances I made. After all, he was much more mature than I was. I could never hope to impress him. He just thought I looked attractive or something. That was all. I couldn't risk his rejection, not when it could affect my job. I had to be on my best behaviour. I fell asleep as I was thinking about this. I had dream, a sweet dream about Namjoon.*

EVENING

That dream was wonderful. When I woke up, I felt ashamed and excited. And it was completely dark outside. Oh, dinner!... I changed into new pair of panties and quickly cleaned myself up. I got all my things tucked away and head downstairs.

IN THE LIVING ROOM

Namjoon was in the kitchen when I got there, sipping a mug of tea and reading something on his tablet.

Y/N: Hey. I was just going to get started on dinner; is that too late?

Namjoon looked surprised, and I hoped I hadn't startled him. I hadn't wanted to sneak up on him, but what was I supposed to do? I didn't want to spend the whole summer creeping around the house and announcing myself before I entered a room.
