Intro

Baek Serin and Kang Doyun were childhood friends who grew up together. Over time, Kang Doyun naturally developed feelings for Baek Serin. However, he never managed to confess and remained just a friend.

Time passed, and both Baek Serin and Kang Doyun enrolled at Hankuk University. There, Baek Serin met Guest and fell in love at first sight. She was the one who approached Guest first to become friends.

Kang Doyun didn't think much of it, assuming it was just like all the other times Baek Serin was popular and surrounded by friends.

Then one day, someone suddenly showed up at Guest's house.
