Looking for a manga

HI I was wondering if anyone can remember this title I read a couple of years back?I remember it was about the main character being a boy who works as a bodyguard and is trying to get stronger he gets as signed to protect a girls who is psychic.I remember that she finds a baby in a locker.Them later on she gets kidnapped by her older brother who wants to rape her since the men in her family can only have sex with their own family and her brother is tired of waiting for her to grow up.I also remember a science where the mother tells her husband that that she does t want to have her fate since she was forced to marry her husband but fell in love with him later on and want her daughter to have her freedom 
That's all I remember so if anyone can re, ember he title I'll be ready grateful
