Third Person's POV

A four-year old Taehyung was waiting for his parents to arrive from the hospital as his mother gave birth to his first younger sister that is also his first sibling as he was an only child for the past 4 years. Their maids are the one in charge to look after him, but right now he is alone in his room while looking outside the window and still waiting for his parents to come home with his younger sister.

Few minutes later, finally he saw his father's car entering their big gate and soon parking it. Taehyung's eyes lit up in joy as he watched his mother go out of the car, carrying the baby girl. He ran out of his room to go downstairs. Taehyung finally get to see his sister and he was so excited. As soon as he reached the living room his parents entered the house.

"Oh Taehyung! Look at your sister, she's so cute. Isn't she?" Taehyung's mother said to him when she noticed the four-year old boy.

"Eomma I can't see!" He pouted and his father laughed.

"Honey he's right, he can't see the baby because he's little."

"Oh, my bad." Mrs.Kim chuckled and sat on the sofa so Taehyung can just sit next to her to see the baby and Taehyung did. His eyes widened as soon as he saw how beautiful his sister was.

"Woww sister is beautiful like me but me is handsome!" Taehyung exclaimed and they laughed.

"Her name is Y/n. Remember her birthday Taehyungie, it's January 3."

"Birthday is close to mine. Name is niceu." The four-year old Taehyung said the last part in English that made all the persons in the big house to 'aww'.

"Lora, can you please take a picture of the four of us?" Mr.Kim nicely asked one of the maids, who gladly said yes. Mr.Kim went to sit next to Taehyung and Lora took their family picture. After taking a picture, they decided to eat lunch together with the maids in one table. Of course they left the sleeping baby in Mr. and Mrs. Kim's room first and laid her on her crib.

While eating lunch, they also talk about adult things. Taehyung was trying his best to eat his meal fast so he could go and see his sister. After eating Taehyung immediately asked his mother if he could go upstairs.

"Eomma can I go to baby?"

"Sure dear, just be careful and don't make any noise okay?" She said sweetly. Taehyung just nodded and hurriedly went upstairs. He entered his parents room and smiled when he saw Y/n's cute sleeping face.

It's Y/n's 5th birthday today. Taehyung slept on Y/n's room last night so he would be the first person to greet her. Taehyung woke up and rubbed his eyes softly, he looked beside him to see his sister still sleeping. Taehyung just turned 9 years old four days ago. Later, there will be a celebration of Y/n's birthday of course and all her classmates in kindergarten are invited and some family relatives. Taehyung had the same celebration on his birthday but he didn't invite all his classmates only his 6 close friends and also some of their relatives.

Y/n woke up and smiled at her brother who smiled back immediately.

"Happy birthday!!!" Taehyung shouted and jumped up and down on Y/n's bed.

"Thank you but oppa stobbb it." Y/n pouted while Taehyung giggled and started singing happy birthday to Y/n. They looked at the door when they heard it opening and it revealed their parents.

"Happy birthday dear.." Mrs.Kim smiled at Y/n and hugged her.

"Happy birthday Y/n!" Mr.Kim hugged Y/n.

"Thank you eomma and appa!"

"Come on take a shower and let's dress you up." Their eomma said and carried Y/n to the bathroom. Taehyung went to his room and also took a shower. After taking a shower he dressed nicely and started fixing his hair, making sure he'll look more handsome than he already is.

A few moments later it was now 12pm and some of Y/n's classmates already arrived with their personal maids. Then after some minutes all the invited guests arrived.

"Okay let's go everyone, let's sing Y/n a birthday song and let's eat!"

"Happy birthday to you~ happy birthday to you~ happy birthday happy birthday~ happy birthday to you~" everyone clapped their hands and started eating. Taehyung was sitting next to Y/n but suddenly her classmate which is a boy, came to her.

"Happy birthday Y/n, here is my gift."

"Thank you Chanyeol!"

"Come let's play Y/n." Then Chanyeol took Y/n's wrist and they went away to play, leaving Taehyung who saw everything and is now feeling annoyed.

"Who was that? Taking away my sister without my permission. How dare he touch Y/n?" He mumbled to himself with his arms crossed. He picked up his fork and stabbed it on the meat harshly before eating it. He doesn't know why but how Taehyung wishes to stab it on that Chanyeol instead.

"Is something wrong Taehyung, dear?" Taehyung immediately went back to his normal expression and faced his mother.

"No eomma, it's just I feel like I can't finish my food anymore." Taehyung lied.

"Oh.. okay then you can go play now, I'll wash your plate." Mrs.Kim said to Taehyung and he just nodded in response. He quickly stand up and went to find Y/n.
