That's better if he did. A piece of shit like her father deserves like that, and sooner or later he was going to have cancer diagnosed anyways.
Her mother is such a bitch too, I'm kinda happy that her legs got broken for a while. What kind of a mother is she?
Ignoring all of her daughter's misfortune given by her own husband who also abused her for many years and had the audacity to side with her husband all the time, and even slapping her daughter, like bro, come on. She can pay the bills on her own then

Okayy? are we just going to ignore the fact someone (most likely yeon-woo) pushed her dad down the stairs
