I feel kinda sorry for her dad though. The MC’s reaction is 100% justified, but still......

Same kind of feel sorry for the dad.. because he doesn't know how to show an affection towards his childrens when they been thought through out their family generation as a strict person especially if you are the next in line to take over the family. That they have to control their emotion and not showing any sign of weakness that could be use against them, they view the emotions or feelings as a weaknesses that they could be manipulate.
