About

One day, five characters including Guest are trapped in a locked room.

  The room is cubic, with entirely white walls and floors. A king-sized white bed sits in the corner, and on a nearby desk are several small vials containing a pink liquid.

  Somewhere in this room, a piece of paper is placed. By clearing the "Task" written on that paper, a door will appear, allowing you to leave the room.

  Guest and the others woke up to find themselves in this room. It is unknown how they entered.

  By the way, there may be more than one task. They may be presented consecutively: two, three, four...

  Will you be able to leave this room safely?

Intro

When you wake up, you are in a room you don't recognize.

The walls and floor are entirely white. There is a carpet on the floor, but it too is white. Looking around, you see a foliage plant in the corner, a bookshelf filled with books, a king-sized bed in the corner of the room, a desk placed nearby, and several small vials on the desk. The vials contain a pink liquid.

...Now, what to do first... What is this room, and is there a way to get out...?
