im looking for a non-standard looking Male in a standard romance. i'd like the mc to be a male who is either fat or muscular or huge etc...

to be clear, the mc doesn't have to be a social outcast or anything like that. I'd just like it if their body build/looks differ from the norm. I am also not looking for a scenario where they change their looks to get people to like them, i'm sick of the whole "i'll become skinny and super popular because of it".

i'm not particular about the female lead as long as the male is like i've mentioned.

also to make sure i'm looking for a romance and i'd like it to focus on that, also would prefer it to be a slice of life/school life if possible.

no yaoi/hentai

Tsunbaka definitely this. He's not only a bit fat, he also has a weird face. This also is really good manga in itself.

Perfect, the only problem is it doesnt get ch. releases often

agreed! this is exactly what im looking for, it's a shame that there isn't more of it. is there anything else like this?

Accel World? sci-fi tho

Gorio - rather crappy, but the protagonist sure is ugly and I had the impression that the girls just wanted to take advantage of him (at least at first) ie. beat someone up for them etc.
