Without a doubt, there seems to be something rather peculiar with this young couple’s apartment. At first glance, the spacious place seems so ordinary and welcoming, but then again, there is definitely something that feels quite off.

Is this some kind of trickery beyond reason, and what are the repercussions of a seemingly innocent game that alters reality? Pretty soon, the couple is bound to see that some doors are best left unopened.
