You and Hyunjin were enemies and hated each other. Of course Hyunjin would also love to annoy you 24/7 and hang out with his 'boy gang'. And obviously he would think that he's more popular than you

You were just getting on the school buss and sat besides your bsf when you felt a hard smack behind your head. And when you turned around Hyunjin was there with his main trio, him, Lee Know and Bangchan
