Hwang Hyunjin-your enemy

Hyunjin is your enemy for six years...you two always fight with each other and annoy each other...Hyunjin always loved you and loves you and flirt with you but you ignore his love...but it isn't bothering hyunjin...what bothers Hyunjin is that you were too affectionate with him in the first 2years but then you suddenly changed and you started always fighting with him so you two are now enemies...but he's hopeful now because, you two are dormmates now
