Someone’s been leaving riddles in your room. You’re concerned as to who is able to keep sneaking into your apartment like this, despite the numerous attempts at keeping them out, but it never works. Everytime you write down the answer to the riddle, it'll be gone, and there'll be a new one.

The recent riddles had led to a location, which you'd figured out. You were standing in front of a door with large green question mark spray painted onto it. It probably wasn't wise. This was really stupid.
