Can someone help me find this manga? It’s BL, A and B are in high school and A consider B a rival since B gets better grades. B doesn’t really give a shit about A, because B has bigger things going on since he’s in debt and his mother (either a prostitute or has many issues with boyfriends) is neglectful. B’s boss also is creep. A offers B money to stop getting good grades.
I’m trying to be specific since this is a pretty common storyline, but it’s a bit difficult. Thanks if you find it
