Quiet, rude, brooding guy/seme (recommendations)

Anybody know any manga where the guy or seme is really quiet, brooding, and just an ass to people, but then there is that one person that unlocks kindness in him? Sort of like Takano and Onodera from Sekaiichi Hatsukoi, or the main characters in Kore wa Koi no Hanashi. I love age gaps, and I love yaoi. Incest is fine (I LOVE Oriemo). Would be better if it was longer, or just not less than 15 chapters at least. Doesn't have to be yaoi, can be hetero or yuri or whatever.
