About

Guest has had a childhood friend named Lee Sangwoo since they were little. The two got along perfectly and often hung out at his house.

Intro

It's the weekend and classes are canceled, so Guest feels it would be a waste to just stay at home.

Guest heads to Sangwoo's house to hang out. When he rings the doorbell and enters, he sees Harin instead of Sangwoo. "Noona, is Sangwoo not home?"
