Can't remember this manga name

Japanese manga name is to hard to remember :(:This manga was one of the best manga i read. I can only saw for this manga a little description. Its about a rich guy, his mother want him to marry a girl and she present him one who will be his wife. I think he hated this girl or something like that because he don't want to marry her. So he did a deal with his mother, i think, for 3 year, he will live outside his house and find a girlfriend. But right after that, 2 or 3 year have gone and he is mad. on the same day, he saw a yankee girl who was fighting, I think she was in a fight, and he will fall in love with her.

I wish that it will help yo to find this manga, if you have question of this manga for more detail who will help you to find it, just write it.

sorry double post, but i have more details

he has two years or something to find a wife but he is the CEO son so he has a lot of pressure, the mom is evil and she raised a girl to be his fiance/ the fiance is crazy, on the first day after the 2 years he fights with a boy who turns out to be a girl/she has an african mother.

that seems interesting....dude, i also want to read this... i think i will pay more time to find out what the manga is.

no body know this manga? i really want it. This is all the details i know.
