Force
Did u even read the chapter? MC never forced him to meet the family... he said that if ML really doesn't want to, then they don't have to. It's perfectly reasonable for MC to at least suggest it, cause they are getting married after all. It's not like MC doesn't know ML has a shitty family.
OP I think you're also just making problems it's normal to ask to meet the family since they are to be married & MCs reasoning were valid but at the end, he tells ML that they don't have to go if he doesn't want to.
If my boyfriend is not comfortable with his family and doesn't want to see them. I would never forget him to let me see them. The mc should know better. Not every family are on good terms. And I know for sure, he is the one who is going to be the most affected once he met his bf family. He's just making problems
