I don't get why they can't just fly over to visit his parents together, the ML has enough money to go back and forth with MC if he wanted to so I don't get why MC is saying he's never gunna come back to his family. Surely the least one of the worst MLs I've read can visit the in-laws once a year with MC or something, he can even flu the family out to MC. IDK seems kinda dumb
