Kim Jongin is the type of person who wouldn't care if you worship him like he's some kind of god or what not because all he cares about is getting into a relationship and getting out of one three weeks later. Jongin gets the adrenaline rush of getting into one and gets just as excited pulling out of a relationship. He sometimes did feel bad for not returning certain feelings towards the other person or making them cry a few times but that didn't stop him from continuing his spree he's been having ever since he started school at Seoul's All Boys Academy of the Arts. The longest he's ever been with someone was three weeks and that's how far he'll take it. Once Jongin meets a quiet wallflower named Luhan, someone who's completely different from all the people he's ever dated, will he change his mind about his three-week relationship spree?
