"What would you do if you found your soulmate, but they had black blood?"
Black blood is a murderer's blood. All people are born with white blood, but the crimes they commit throughout their life darken it. The worse the crime the darker their blood will get.
Ali is the perfect role model student. He has good grades, he's on the track team, he does volunteer work, and he's kind to everyone. It's expected that he has light pink blood, but nobody has ever seen it.
Except Corey.
Corey is the average kid, red blood, doesn't do his homework, probably committed a couple crimes here and there. What he doesn't expect to see is Ali's blood, everywhere, and a surprisingly unexpected color at that.
