Childhood friends Rui and Yuki, who share an unbreakable, complicated bond, found themselves trapped in a pure white room with no doors.

A solitary table sat in the room. On it, the two discovered a letter.

Upon reading it, they found it stated: "This is a room you can't leave unless you have sex."

This is something different from a youth spectacular, depicting how two individuals right in the throes of puberty escape from "the room you can't leave unless you have sex."

It's wholesome.
