Please Helpp

I've been looking for this manga for such a long time because I wanted to give it a re-read but I forgot its name. I remember it was a black and white manga about a young boy who's from a rich family (I think), so he has this friend whose job is to protect him and be his bodyguard sort of. Keep in mind they're the same age.
And I remember how this boy wanted to be a princess because he read fairytale stories and he just wanted to find another guy to be his prince and him being the princess, (I'm trying my best to recall as much info as I can). So, the two boys end up going to school and eventually end up together... I know this isn't a lot to go off of, but if anyone remembers or knows which manga I'm talking about, please help!!! It would be very much appreciated!! ((>///<))
