One thing I'll never understand is that she never even told him he has a daughter and he missed 14 years of her life. And yet, everyone in the whole drama acts like she was the one who was wronged. Including the male lead and their daughter. Like, what even.
"women are the most violent"? OMG are you kidding me! That's your personal , rather distorted and biased, opinion. Do you have any idea how many women die at the hands of men every year? Do you know how many rape cases and domestic violence cases are registered every day? And most of them are men inflicting the suffering! Stop your bratty behavior when you have no idea about female suffering.
And as for the drama, the reason they tried to project the man being bullied by women is precisely to highlight your opinion that men can be beaten up by women too and just don't generalize because of facts and statistics. But reality is, Korea has a lot of domestic violence cases and they have gender-based hierarchy in their culture.
The more I watch the more I feel he didn't kill anyone. He just has anti-social personality disorder thanks to his childhood trauma. Maybe the reason he is on the run is because his sister killed the village foreman and clearing his name would bring her trouble.
