I don't think because his brother are an intellectual person and the school of the roomate are for idiots

good point. their school is literally a prison(￣∇￣")

lmaooo truth literally a prison

Its not possible
Poop head and baebl has same age, that roomate is poop head's classmates.. so they got same age, so he must be not his brother
