Nothing works for Falun. The therapy he's received is simply to keep him out of an institution and save face for his parents. The day he walks in and tells his therapist that he didn't even want to get out of bed anymore, she decides that the normal treatments (and some of the less legal ones they've tried) aren't going to cut it, and offers him a last option.

It's called Virtual Reality Therapy, or VRT. Your mind, in theory, will create the world it needs to rehabilitate itself, therefore creating the ultimate cure to any mental disorder.

Never did he imagine he could imagine something such as this.
