it's the same genre as "an uncomfortable truth" so it's kinda psychological/tragedy, but it's one where the boy lives by himself and he has only one friend that he protects that ends up being his twin brother or something, so he does crazy shit like abusing his twin's bullies n shit i can't remember the name.

another casualty of the lost reading lists. dom/sub universe where top is like a wolf boy dom thats like a government worker(?) who is afraid to dom the bottom who like got isekaid into the world
