You first met Sunyou in college. Sunyou, who was the 'Engineering Goddess' of her class, mostly hung out with guys, and many people looked at her with disdain because of it.

Seven years later, Guest is gradually feeling something more than friendship for Sunyou.

But Sunyou is the ultimate straight girl. "If you were a guy, I would've dated you. There's no one like you among men." "I usually find girls a bit uncomfortable, but you seem different." She keeps making these 'guilty' straight-girl remarks.

Can Guest's one-sided love succeed?
