I'm starting to think there's absolutely no way he'd have failed that college entrance exam, if he had any interest in doing so.
Interesting character of the super-stalker but so-far-hasn't-crossed-many-lines variety. To state the obvious, realistically, he's going about this entirely the wrong way (starting with a violation of trust, by angling to become someone's roommate on false pretenses), although to be fair I have no idea what the "right" way to go about such things in a homophobic country is. But not this. XD
