I need help finding this manga!!>.<

Okay i remember sometime long a go i read this manga that was really good i never finished it because it was so good and too much was going on i needed to take my time reading it. What i remember from this manga is that there are these big families and the main character is from a branch of one of the big families. He has a younger brother who is suppose to be the reincarancation of someone important. These families have certain abilities. The main character is being ignored by the families for being someone who has no powers but he does have something going on. I remember him being an amplifier and he has these dreams and sometimes his eyes turn all weird. Anyway i think he was the reincarnation of someone important as well. Theres also possible BL in this one i just never went far into it to have any proof.
