The college lecture hall buzzed with noise as students filled the seats, laughing and chatting. Jungkook slid into the last row, backpack on his shoulder, notebook open but untouched. He kept telling himself it was just another ordinary class, but his stomach twisted nervously. Today, a new professor was taking the course—someone everyone had been whispering about for days

The classroom door opened, and the noise died instantly. Kim Taehyung stepped in, tall and composed, carrying a stack of files. His sharp gaze scanned the room as he spoke, calm but commanding

Whispers spread among the students immediately.

Jungkook’s eyes widened involuntarily. Why did everyone sound so calm talking about this? And why did his chest feel like it was about to explode?

He tried to focus on the board, taking notes mechanically, but every sound, every movement from the professor seemed to pull him away. Even the way Taehyung adjusted his files made Jungkook’s heart skip.

Midway through the lecture, Taehyung’s gaze shifted across the classroom and landed on Jungkook. The room suddenly felt smaller, warmer, and heavier.

Jungkook froze, his pen slipping slightly from his fingers.

Taehyung’s eyes met his for a fleeting second, intense and unreadable.

The words were simple, but they struck him like thunder. Jungkook quickly lowered his head, cheeks burning.

The lecture continued, but Jungkook’s mind refused to follow. Every step Taehyung took to the board, every turn of his head, made Jungkook’s heart race. He tried to take notes, tried to act normal, but it was hopeless. Finally, the class ended.

Students immediately gathered their belongings and rushed out, whispering excitedly about the new professor. Jungkook stayed seated, staring at his notebook, barely breathing.

Jung Hoseok (Male Best Friend – Sunshine Support) Name: Jung Hoseok Age: 22 Role: Support Character Position: College Student (Dance Department) Family: Close-knit family Personality: Cheerful, supportive, energetic, emotionally intelligent Like: Dancing, street food, making people smile Dislike: Seeing friends hurt Hobbies: Choreography, vlogging Love: Slowly falling for Kang Yura Friends: Jeon Jungkook, Kim Seokjin Appearance: Slim build, bright smile, casual street style Weakness: Hides sadness behind smiles

The moment was silent, yet electric. Taehyung collected his files and gave the class one last glance, lingering ever so slightly on Jungkook before leaving the room.

He grabbed his notebook with shaky hands and left the lecture hall, trying to act normal as the campus noise returned around him. But the image of Kim Taehyung—the calm, sharp, impossible professor—stayed burned into his mind. Even walking through the campus, Jungkook felt it—the strange pull, the nervous excitement, and the flutter in his chest. Today had been only the first class. Yet, somehow, he already knew his life would never be the same.
