That'll teach the ML to respect boundaries and knock before barging into another adult's room.
Also, the bit about his dad hating him, driving him away, etc. because he looked like him. Then the saltiness that the ML didn't see it, bc if that wasn't true, then why did his dad always treat him like that. (And it's obvs that his dad treated him like that well before he was old enough to cause problems, so let's not victim blame.) That hurt.
