I have to agree, this is the ONE instance where the mother is actually justified in her actions. Her son (read: daughter in our world) is literally fucking around with at least 2-3 different girls (read: guys in our world) And wants to marry them all while still in high school. Any sane parent would go nuts XD
And she should be thankful she does not know the really fucked up things, like the drug cartel owner blackmailing him into sex, the people who want to kill him and all that shit XD She would get a stroke if she did.
Also to be fair, even though he never says no to all these girls, the MC is doing his best solving all the shit that has been flying around, mostly kicked up by his sister.
Let us hope we can have some calm now, so he can also get some training in, cause you know, he has 6 months to do so or he dies...
