I Seem to Be a Player

The protagonist transmigrated. He's a transmigrator, but not entirely: he's stuck in a higher narrative dimension, where countless versions of 'him' exist simultaneously in different worlds. But he hasn't 'split apart.' Those countless versions of 'him' are all parts of himself. He is 'them,' and 'they' are him. Each of those versions is an entirely different game character, in a game that has either just begun or already ended. Every world they inhabit is a separate server, a new or old game. He is merely a [Player] stuck in front of a 'computer,' forever unable to leave except by entering a game.

PS: I'm terrible at writing introductions, and this part may be revised later. Please forgive me~ (>人<;)

Also, the protagonist really is a transmigrator. He's not a native who transmigrated after suddenly gaining an identity and a transmigrator's memories, nor has he truly 'lost his memory' or forgotten his past. This will come up later. In the story, the protagonist will make references on purpose or in passing, and he knows the plots of various works of entertainment, at least as an online fan who knows them secondhand.
