Dear Door
Alrighty... when I next come back to this, here's what's going on... Human dude is a 'doorway to hell' - which will be opened when he climaxes >.> = generally possible through the demon saying his own name which is a form of sexual-vampire-ish-aphrodisiac - but currently demon dude has been stabbed with an angel's shard (which is attached to his heart) which leech's his powers so he's been forced to do sex the human way. Human dude 1 [Gooyeong???] is not having a good time with this whole thing. Human dude 2 [Jin?] is the best friend. Currently he's not having a good time because he found demon 2&3 (assumed ally and enemy of demon 1 [Cain] - but actually working together) together and demon 2 made a bet about whoever dominates the other wins (survival vs you're mine D:) - but demon 2 magic hypnotized poor human 2 into thinking demon 2 was his sexual desire - which took the form of human 1. Mainly I'm going - I'm kinda down for more kinky scenes with demon 1 and human 1. But I'm also really hoping that the humans survive and get together. Somehow.. Kinda pissed at demon 2 for being a traitor.
