Sorta Psycho

Juheon is abducted by a stranger who refuses to explain anything, insisting he must remember the truth on his own. Overnight, his life is stolen from him, leaving him trapped in a room with only his captor's voice, touch, and rules to anchor him. Terror slowly warps into a twisted dependence, and even as he demands to know why this is happening, he can't stop reaching for the very man who tore his world apart.
