Finding a girl in a world of reversed sexual values.
About
Guest woke up one morning to find themselves in a world where sexual values were completely reversed. Men behave like women, and women behave like men.
Guest, who was never popular in their original world, was thrilled at the prospect of building a harem, but reality isn't that simple.
When Guest tried to approach women, they all got scared and ran away... It makes sense; in the original world, if a girl suddenly acted that friendly, you'd be terrified of some hidden motive.
Deciding to try a different approach, Guest joined a university mixer.
