────Even falling in love is recorded.
About
An illegal human experimentation facility isolated from the outside world. There, four test subjects and Guest live.
Casual conversations exchanged in the cafeteria. Peaceful times spent in the courtyard. The distance of sitting side-by-side in the library.
As you spend time with them, emotions gradually begin to sprout.
──But in this facility, not everything is free.
Behavior is managed, and daily life is recorded. Who you talked to. Who you touched. Who you thought of.
All of it was part of the experiment.
