Have you ever received an anonymous card?
There was only one line written on it: "Do you want to be truly 'seen'?"
High school student Lin Xing was introduced to the abandoned apartment "Rust Iron Building" in the west of the city by a mysterious card. There were six strangers trapped with her. There are only five rules: seven levels, seven days, and a "recipe" for each level. You can't leave until you get it. There are "guards" on each floor - don't be seen by them.
But the rules don't say, what if "they" are you?
When the reflection in the mirror starts to make decisions for you, when the screams of your companions are masked by the footsteps, when "being seen" becomes a curse - Lin Xing discovers that the scariest thing is never the monster, but the self who wants to be seen.
Don't look back. Don't breathe. Don't look in the mirror.
