Instinct, Jealousy For Someone

Classes Start With Bell Rings

The lecture hall buzzed with murmurs as the professor stepped in. Without delay, he spoke firmly.

“I'm Jake your professor buy now till the end of your graduation." With a bright smile on his face. Announce the important thing,"Those who were paired during the buddy system will also be partnered for your first group assignment. Whenever I give you works, you must be work together and submit it by next week. Class begins now.”

The announcement caused some groans, but Ken’s heart thudded slightly. So, I’ll be working with… him again?

The lecture rolled on. Fah sat two rows ahead of Ken, his broad shoulders relaxed, but his sharp eyes occasionally flicked sideways—almost as if sensing something.

By the time the lecture ended, the professor handed out assignment topics and dismissed the class with a reminder:

“Use this break wisely. I’ll be expecting thoughtful work.” went out of the classroom while all the students were standing and saying together, "Thank you, Sir." with a smile because this is a Recess Break Time.

Break Time – At the College Canteen Courtyard

Outside the class, Ken tugged at Khao’s sleeve.

“Come with me. I need to check on someone important.”

Khao tilted his head curiously, following Ken past the hallway, down the back garden toward a shaded bench. An older man, the campus gardener, was sitting with a small, wagging bundle in his lap.

“Uncle!” Ken waved. “Is Yuki okay?”

The gardener smiled, handing over the puppy.

“This little one didn’t move from the spot all day. He just waited for you, ears perked like he was guarding something.”

Ken’s smile softened as he held the puppy in his arms.

“Thanks again for taking care of him.”

Khao blinked in surprise.

“Aww… Cutie! What’s his name?”

Ken chuckled, kissing the pup’s head.

“His name’s Yuki Tanaka. He’s my one of family member now.”

Just as he said those words, a warm breeze rustled the trees.

From across the canteen courtyard, Fah had just stepped in, lazily walking beside Thee. Fah wasn’t looking around and listening to Thee who was making jokes of freshers until he heard that voice. He paused—eyes narrowing slightly searching for the person's voice—and turned toward the bench.

There, under the dappled sunlight, stood Ken, cradling a puppy, his smile so radiant that it stole Fah’s breath for a second.

"He… looks so happy… and gentle." Fah said that with a bright smile he never give to anyone after his grandfather died.

Thee, meanwhile, stopped mid-step—his eyes widening when he saw something rare.

“Fah…” he whispered, stunned. “You’re smiling.”

Fah didn’t realize it himself. It had been years. He hadn’t truly smiled since his grandfather passed away. The expression came naturally as he stared at Ken.

At that very moment, Ken looked up—and their eyes met. Neither moved. Neither blinked.

The world felt distant. Only the sound of their racing hearts pounded louder than anything else.

"Why is he smiling at me?" Ken mu

"Why do I feel warm?"

They both looked away, cheeks flushing slightly, pretending nothing had happened.

Later — In Separate Classrooms

Classes resumed. Fah and Thee were in another department, while Ken sat beside Khao in theirs. Yet even separated by buildings, neither could focus—their minds replaying that moment from outside.

After Class — Outside College Gate

Ken and Khao walked to the gate together.

“See you tomorrow,” Ken smiled.

“You too! And give Cutie—I mean, Yuki—a hug from me!” Khao giggled.

As Khao left, someone leaned casually against the gate’s pillar.

“Took you long enough, huh,” said a familiar voice.

Ken’s face lit up.

“First! You.... waited?”

Puitrakul "First" Tanaka, Ken’s elder brother, looked slightly annoyed… and flustered by his words.

“Of course. It’s your first day. I’m not a monster and I'm your elder brother who took responsibility, right.”

But then his tone turned sharp.

“That boy you were talking to. Who is he? A new friend?”

Ken tilted his head, suspicious.

“Why are you suddenly so curious? You’ve never cared about my friends before.”

First crossed his arms, looking away.

“I… I met him earlier. Accidentally when I was exploring the town in morning. His face—there was something about it. The sunlight hit him just right, and I just knew…”

“…He’s an Omega.”

Ken’s eyes widened in realization.

“Wait—you mean Khao?”

First nodded, his cheeks tinged slightly red.

“He didn’t tell me his name. Just apologized and ran off.”

Ken sighed and laughed softly.

“So you’re acting like this because… you fell for someone?”

First shot him a warning glare but then looked away, quiet.

“Maybe.”

"You should’ve started with that. Let’s go home. You can tell Dad together.”

Ken placed Yuki gently in his brother’s arms.

At that mean time Fah was about go to his way Home. Fah was in his black car and set at drive place. Fah suddenly hear familiar voice - looking around him from car window and saw Ken laughing and talking to a boy.

But he didn't listen clearly what they were talking about.

"Who's that boy."

When he heard horn sound from back of the car he drives from their to on the road.

At Ken’s House

Ken and First sat down with their father, introducing Yuki, the newest Tanaka family member. Then First hesitantly opened up about his feelings for the boy he met suddenly, whom Ken confirmed was Khao.

Their father smiled warmly, giving a nod of encouragement.

Elsewhere, — Fah’s Home

Fah's POV

Fah ate dinner alone. His parents were away again.

The quietness in the house made every thought louder.

He couldn’t stop thinking about Ken.

Why was I staring at him? Why did his smile make me feel warm?

And then he remembered… Ken wasn’t alone. He was talking to someone else.

A boy.

And laughing.

Enjoying his company.

Fah clenched his jaw.
