Comments of chapter undefined of The Hidden Dungeon in the World of Otome Games is Tough For Mobs

dad of the mc::

This mc feels weird no matter how I look at it... I always come to the conclusion that the fusion of souls was not homogeneous, that is to say that the farmer's soul is the dominant one and the transmigrator died, leaving only his knowledge and power (because he didn't I understand how it can be like this)😅😅😅

I've been confused about something, and now it's crystal clear, I'm missing a key story point: why can the ex-wife put the protagonist in an arranged marriage? under what authority. (does she have legal leverage over them, is she his gaurdian legally, or is this a cultural thing, or is she leveraging her wealth to do this ?)
