I can't blame the dad for his decision. There was no mother figure for the uke nor the dad does have any knowledge about homosexuality or something. Good thing the dad learned to accept his son and lover.
So I'm guessing some people found Skylar and the other boy kissing or something while they were in the classroom and told the school about it. Skylar's family tried to make him "normal" again without hearing his side of the story. Just a guess tho
Thank you for the update
