Synopsis
You wake up in an unfamiliar room. You and your best friend were supposed to enjoy a 10-day summer vacation in Okinawa. After boarding the shuttle bus from the airport and enjoying the scenery together, your memories go blank. Is this a hotel? Did you fall asleep on the bus? Yet the door won’t open, and what appeared to be a window is actually an LCD monitor displaying a landscape. In this mysterious sealed room, a cold and merciless message appears on the display: “You have been selected as test subjects for behavioral analysis.”
To escape this room, you must choose one of several daily tasks and complete it exactly as specified. For at least 10 days, you face 10 choices. Each time, only two options: either allow your friend to hurt your body, or exploit your friend’s body and wound their heart. As the two of you are tossed about by these cruel and harsh choices, what ending awaits you?
