½ = How the character feels about people taller or shorter than them
Not a lot of people are shorter than Shuu, so he finds it a nice change of pace. He likely won’t say anything about it, though. He’s used to people being taller than him, but can still become self-conscious about it quite easily if you bring it up.
♥ = Character’s preference for relationships (sexuality, type of person, etc.)
It’s a little fuzzy. As far as the bedroom goes, he’s just so extremely gay it’s not even funny. He tried it once with a woman when he was a bit younger and it just so completely did not work out. At all. But, he does find femininity very aesthetically pleasing, and if he likes you well enough, he’ll probably be willing to try a relationship based on that. Bedroom fun is just gonna have to be a no-go (with him, at least - he’ll discuss an open relationship). He’ll definitely need a period of time to get acclimated to the affection too, as he’s used to the company of guy’s guys. The beginning of the relationship will likely be a bit awkward in this regard, so just take it easy on him.
As for type of person, he’s really into intellect, so the smarter you are the more in love with you he’ll be. But then again, he’s desperate enough to be likely to settle for anyone who gives him the time of day, so don’t worry about it too much. If you just pay attention to him, being kind and smart are both more for bonus points, the former likely more so.
⊙﹏☉ = What flusters the character
Unexpected shows of affection. Do something out of the ordinary to show you care and he’ll quickly become a blushy mess. Going the sexual route - flirting, dirty jokes, etc. - varies in effectiveness. He’s a pretty sexually liberal guy, so just bringing up sex as a concept likely won’t be enough. Use a bit of imagination though, and it’s not hard, especially if you’re in public.
(;へ:) = What makes the character cry
Too many things. He’s one of those people that will start tearing up even when they don’t actually feel like they’re upset enough to. It definitely doesn’t take a lot, just pop in a sad movie or, if you’re feeling like a jerk, heckle him a good bit and stress him out. He doesn’t need to be sad, just worked up enough for his eyes to start watering. He’ll likely do everything he can to remove himself from the situation before you see him like that, though.
