because the kid does not want to have a debt with him for paying everything and for letting him stay in the house, he needs excuses if not, the kid would get out from his house also, remember that the mom asked him to let the kid stay until she paid off her husband debts that's why he is doing everything to make sure the kid would stay
Honestly if he wants the kid to go to school so bad and to depend on him why does he keep saying that he’s gonna charge the kids mom for everything the mc gives him and that he didn’t take him in for free and to be nice
