📚 General Synopsis
In a modern high school veiled in silence and secrets, Ren Takami, a boy who survived a mysterious suicide attempt, returns for his second year—missing part of his memories and all sense of self. What no one told him is that the forgetting may not have been accidental.

In this world, memories can be stolen, sold, or sealed away. And somewhere in the school’s past, a hidden emotional manipulation program twisted the lives of several students. Now, they're connected by pain they can't explain… and by a room no one speaks of: Room 4-C.

As Ren digs deeper, whispers of a girl named Sae begin to surface—someone who "disappeared" without ever leaving.

Ren's psychic ability starts awakening: he can feel the emotions embedded in memories. But the stronger it grows, the more reality slips from his grasp. The more truth he uncovers… the more he forgets who he is.
