Help me find the Anime I am looking for.

[Shloot]

Well a few months ago I started watching an Anime of which I the name don't know anymore so I am trying to ask you guys here which anime it is. I will discribe it a little.

It is about a boy who lost his father and will eventually take over his father big company the company is apperently really famous. The boy will be send to a school and there he has to find a girl to marry him so he can get the company. But while he is on that school he finds out that he has a little sister. That sister is calling him on his phone and he is trying to find out who she is. The girls on his school love him and want to marry him aswell.

I hope I explained it good enough if not ask me for things.

Sorry about my English.


Thanks in advance .

I think I got this...
It's "Kono Naka ni Hitori, Imōto ga Iru!" ("My Little Sister is among them!) ?
