A forbidden love (Jeon Jungkook)

The rain was falling lightly that night. Bella was alone in the library, engrossed in her work. Or at least trying to be. Until she heard familiar footsteps.
"Still studying, Miss Bella? " The deep voice made her hold her breath. She looked up. He was there. Without his formal suit, just a white shirt with the sleeves slightly rolled up. Too close.
— Always, professor.
The silence grew heavy. Heavy. It wasn't just tension. It was something deeper. Something that grew with each passing day, something they pretended not to feel. He took a step back.
That's not right.
She swallowed hard.
Feeling is not a choice.
The sentence came out before she could stop it. His eyes darkened slightly with uncontrolled desire, but also with conflict.
"I would never cross a line with you ," he said firmly . "You deserve something clean. No shadows."

Every college has that one professor.
The one who enters the room and the murmur dies down.
The one who speaks softly, but everyone listens.
One who embodies elegance even in silence.
His name was Jeon Jungkook.
Professor of Contemporary Literature, 30 years old, always impeccably dressed, with a firm voice and a discreet smile. Kind. Polite. A gentleman even when he didn't need to be. He didn't try to be admired—he simply was.
And all the girls knew that.
But there was one that she didn't just admire.
She could feel it.
Bella was 18 years old. The class nerd. Always in the front row, always with the right colored highlighters, always with answers ready before the question was even finished. Intelligent. Sensitive. Quietly intense.
She fell in love before she even realized it was love.
It was on the first day.
He entered the room.
She looked up.
And the world seemed to shrink.
But there was something Bella didn't know.
When Jungkook's eyes scanned the class that first day... he stopped on her.
It wasn't her looks — although she was naturally beautiful, without any effort.
It was through her gaze. There was depth there. Focus. A concentrated sweetness.
And in that second, he felt what he couldn't feel.
