It's a bl, I think chinese. I think its related to dragons and pearl or something like that. The mc is searching for the pearl and a black dragon or something. The mcs partner is that black dragon. I think they go to a highschool and the mc has a man who he calls grandpa ( he looks young though) and there was a relationship plot between this guy and the mcs brother. The guy hates the brother. And the brother has forgotten about that guy. And I think the mc has no powers or something like that
