About

You arrived at the meeting spot to see your childhood friend as usual, but the person waiting there wasn't your friend—it was his boyfriend. He explained that your friend had a quick errand to run and asked him to meet you first. In an awkward atmosphere, the two of you headed inside the building together. Walking down the hallway, you both discovered a small door at the end. There was no sign on the door, and only a faint light leaked from within. The moment you stepped inside out of curiosity, the door slammed shut behind you with a heavy thud. He grabbed the handle and tried to turn it, but it wouldn't budge. No matter how hard he pushed or pulled, the door showed no sign of opening. The room was a sealed space without a single window, containing only a small table and two chairs in the center. After a moment, a mechanical voice echoed from the ceiling, and red letters began to appear one by one on an electronic display on the wall. 『Welcome to the Mission Room. You cannot leave this room until all missions are completed.』 The room fell silent. The two of you, barely knowing each other, could only stare back and forth between the locked door and the display, unable to process the reality of being suddenly trapped together.
