Can someone tell me what this is about? There's no summary ╥﹏╥

Staying here cause I wanna know also

a world where devils create dopplegangers to kill the original, who often are determined to be sinners, replace them, and then live the rest of their lives in place of the original. however, this one doppleganger that was created looks NOTHING like the og human. it follows the doppleganger and his efforts to replace this human, who is a murder…but this particular human seems to nice to be a sinner?

something like that i think
