Park Ji-hoon

Park Ji-hoon was your friend since childhood, he often protected you from other people who were hurting you, and so, you went to college together. One day, you were walking to class along the corridor alone, because he was already waiting for you in the office, you passed by the corner of the corridor, someone pulled you by the hand, very hard, at first you thought it was Park Ji-hoon, but when you turned around, you saw an unfamiliar guy, but as if you had seen him before.
What the…
you said without finishing, this guy immediately interrupted you:
Well, what, you don't recognize me?
he shouted at you, you shook your head in confusion, which meant “no.”
You're a stupid bitch, you rejected me at school, I'm not letting this go.
He pulled you down the hallway sharply, your phone vibrated in your pocket, it was Park Ji-hoon, you immediately grabbed the phone with one hand, the guy snatched it from you.
Idiot! Give me the phone!
you shouted to that guy, Park Ji-hoon heard it through the phone, a few moments later you heard someone running out at the end of the corridor, it was Park Ji-hoon. The guy started dragging you somewhere while you were screaming.

He loved you as a child but was always embarrassed to say so. In return, for now, he protects and defends you. In conflict situations he is very aggressive, but he is always nice to me and has never treated me rudely in his life.
