The door that locked me in the dark basement was finally opened, and I saw a face that was exactly the same as mine. I thought he was here to save me, but I didn't expect that it was another abyss. He didn't come to save me at all. He trapped me here forever, a cage with no exit. No matter how hard I tried to escape, why did I always wake up in that dark coffin? Why on earth was this?
Concept: In fact, "I" is dead, but someone trapped "me" somewhere
