Pure Love Operation

Synopsis

I witnessed my boyfriend and bestfriend kissing. It happened to be with the unlucky classmate, "Ko Eun-hyuk" . 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"?? Su-Ae trying to change her fate, and Eun-Hyuk who is caught up in such a plan, goes head-to-head! I was only trying to pretend to be in an affair but I'm getting really into it?! This plan... will it work? Source: MU
