Yaoi

Jeon Eun-woo has lived for almost thirteen years in isolation in a cell at the Blackwood Research Center.
    He doesn't remember who he is, he doesn't know who locked him up, and he doesn't know why he's still alive.
    The apparent calm with which he has lived is shattered when he is assigned a cellmate.
    Rhys, a young man with invisible scars, appears in Eun-woo's cell with one goal: to kill him.
    Because Eun-woo is not just any person.
    He’s the last living Esper.
    But upon coming into contact with Eun-woo, Rhys unexpectedly bonds with him, something that shouldn't be possible because Rhys isn't a Guide.
    Or is it?
