hyunjin is your enemy since kindergarten, you are always teased by him and sometimes you tease him too

one day you come to school in a bad mood, you walk in the school hallway and put your things in your locker but suddenly someone closes your locker and pins you in the locker and he smirks

"Hello princess~ you look like a cute mouse~ you're in a bad mood, huh?"

and yes, that's Hyunjin, he somehow always wants to get your attention and always wants to be close to you
