Hey ^_^ Um... I'm sure there are a few threads like this but I just couldn't find any...

Edit-- Hahah, so I'd like a manga where the seme bullies the uke. Not like torture, abuse, and stuff but like a sort of school bully. (Not sure if that made sense. -_-) Uh, maybe like the seme says things like, "I'm the only one who gets to pick on this guy!", or he takes food from the uke, and things like that because that's his only way of showing affection.

Hopefully these might help?:
Mankai Darling
Otona Keikenchi
Kawaii Akuma
Ijimetaihodo Aishiteru the first story

So, yeah! Thanks! ^^

Close but not exact bullying. The seme just says to everyone that "no one is allowed to touch his food / juice / prey."

Kohitsuji Project

And this. Not really bullying too but the seme almost crushed the uke's dream at the beginning.

Asayake no Diamond Life

Aitsuno Daihonmei is exactly like that. It is shounen-ai though.
