Ok, this is just retarded.
I kinda get that he wants to protect his crush or whatever, but that is not just affecting him, but also his mother and sister.
If he was like a guy alone without parents so it would not affect them i would be ok with that, but obviously he's not, and his crush doesn't even love him in the first place, she's just pity of him and she's the main cause his life is ruined and even sometimes she tries to blame him because there's rumours in his school that might affect his perfect reputation.
