I witnessed a kiss between my boyfriend and my best friend. It happened to be with the unlucky classmate, "Ko Eunhyuk." I'm already confused. Each person has a fixed amount of love for life? Even the amount of love I can get is "0"? You know, Su-Ae trying to change her fate, and Eun-Hyuk's plan to fight back! I was only going to say "Telephone" for cheating on me, but I'm getting attracted to it This plan... Can I succeed?
