It's not that I don't get you but try to think in the dad's POV.
He's a tyrant king who had an arranged marriage. No feeling involved here. He doesn't know how to love yet at that point.
Not that his feeling didn't exist but he didn't know how to express it. The first wife is not expressive either and didn't help him in finding love. Only when his second wife came in his life that he learnt how to love. Recall that only she could calm him down before.
It you were at his place, can you still say that?
I mean yeah but what does that have to do with being a shifty parent. I feel so bad for the son cause it looks as though not a single person cares about him and everyone only cares about the mc...I swear the mc is the only one who gives a damn about him...he's just a little kid he doesn't deserve that
Lmao ik I'm new but, for me, the FL is annoying for now XD also, plz don't blame all of them. The dad tried his best to connect in his own form of "love" that he knew, + the passing of the title? That could be change when she's older (just announced it publicly so she won't be taken) the son was never neglected ( you can see their interaction my friend!)

My heart ache when the dad distances himself from her because of her outburst without knowing the reason for like a month. I know he annoyed her but I don't like the sad expression from him. He already lost his wife and his daughter treated him like that. I get that this is comedy but it's not good to prolong the fight no matter how much you try to emphasize the cuteness.
