I think that Sumikawa Kaichi is a biromantic demi-sexual. The way he dated a lot of girl, loved them, but didn't want to make love to them sound really asexual and since he always say that Miharu is the only one he sound more demi-sexual than gay. Well, that's an opinion form a biased person, but I think this couple would be even more awesome that way. Ｏ(≧▽≦)Ｏ
