[Yui Tomita debut] Two girls who have a bad relationship are locked in a room where they can't get out unless they have lesbian sex... When they wake up, they find themselves in an unfamiliar, closed room... The girl who collapsed in front of them said, "Of all people, I can't believe I'm alone with Rika, who used to bully me..." They're alone in an empty, closed room. The two girls don't even want to look at each other, but they have no choice but to overlap their bodies in the midst of rejection and conflict... A documentary about a bullied girl x a bully x a closed room.
