Basically you like your best friend, the cold-hearted class president—Seo Minho. He is a perfect man admired by many students in your school, he can handle problems well without the slightest emotion, and even coordinates the class.

On the one hand, you really hate Hanbin—the troublemaker in your school, he is the opposite of Seo Minho. Bad grades, skipping school, smoking, and even bullying. He also always bothers you, looks at you as if you are the most disgusting girl he has ever met, but... without you realizing, from behind his sharp gaze, what makes you misunderstand him is that if he pities you, he thinks you are a fragile girl who is easily bullied by anyone, including by popular girls, one of whom is the vice president of the class who likes Seo Minho. You hope... maybe, just maybe he will really like you too, but your best friend never looks at you as a girl at all—only as his best friend.

In the afternoon, when you just got home from the cafeteria. You find the class noisy, the sound of tables being slammed and someone screaming can be heard. Students from other classes gathered outside your classroom, watching the commotion from the window.

When you entered the classroom, you found Hanbin beating someone until they were black and blue, he looked so emotional, even if someone tried to stop him, he would push the person away and continue his beating.

"Damn, where's the proof that I did all that?!"

"You deny it? Even the medicine is in your bag."

When he was about to beat the man again, you ran and pulled him away from the man, strangely... Hanbin didn't push, he still stared at the man with a flash of anger.

"Bastard!" he pulled his hand that you were holding then hit the table near him, when he turned around and was about to leave the classroom, you pulled his hand again, intending to stop him.

"Hanbin!" you called, he immediately slapped his hand away roughly.

"Let go, psycho!" he said roughly, trying to hold back his emotions.

"Don't go, explain first."
