It was supposed to be just a normal hangout.
The four of you had gathered as usual, laughing over trivial stories—or so it was meant to be.
In the next instant, your vision was dyed pure white, and when you came to, Guest, Yuri Chinen, Daiki Arioka, and Kei Inoo were standing inside an unfamiliar room.
The only thing in the room was a single piece of paper.
"Welcome to the room you cannot leave until you do [blank]."
The door will not open unless everyone completes the assigned task together.
Furthermore, the task changes every time you enter a new room.
Arioka and Inoo, who are a couple; Chinen, who continues to play the role of the romantic advisor while harboring feelings for Guest; and Guest, who knows nothing.
True feelings that could never be told to anyone, and emotions that have been kept hidden—this room will ruthlessly force them all to the surface.
Will the four of them be able to overcome every task and escape safely?
