im looking for manga where the main male character is extreamly protective of his partner for example like Kouro in love monster and ma-kun from faster than a kiss, where you just dont mess witht hem for fear of death

have you tried black bird?

100% Perfect Girl since the guy insist she has lots of bodyguards everywhere

ive read S.A, and im in the process of reading black bird, and yea they are like what im wantnig thanks so far

I actually liked Kaichou wa Maid-sama more than Special A... but this is all based on the anime I've seen...

Manga-wise... (all of which are completed works)
Ai Hime - Ai to Himegoto was pretty sweet... not crazy love-drama... just love...
Hanatsukihime is a good one too!!
Kiss/Hug -- he's pretty possessive...
Midnight Secretary - smut warning
