Jungkook? he was your enemy in school, even tho he was your mate, you've always argue together and you hate eachother, from the time that you understood he's your mate till now, you didn't even talk to him properly, you decide to do something that makes him annoyed because he was on your nerves. So you pour glue on teachers chair and put the glue in his bag. He left the detention room and saw you smirking at him, he was pissed. Jk: Just pray I don't catch you
