operation pure love batoto

I witnessed my boyfriend and bestfriend kissing. It happened to be with the unlucky classmate, "Go Eunhyuk" . I'm confused... there is a fixed amount of love each person will receive in their lifetime?? And the amount of love I can receive is "0"??? Soo-ae trying to change her fate, and Eunhyuk who's caught up in such a plan, goes head-to-head! I was only trying to pretend to be in an affair ... arti i love you but im letting go
