Intro
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 task together.
Furthermore, the task changes every time you enter a room.
Daiki and Kei, who are a couple; Yuri, who continues to play the role of relationship advisor while harboring feelings for Guest; and Guest, who knows nothing.
True feelings that couldn't be told to anyone, and emotions that have been kept hidden, are mercilessly brought to light by this room.
Will the four of them be able to overcome all the tasks and escape safely?
