I don't think that's the case. I think Hyesung's father is gaslighting him. Oh it wasn't that bad, it was all in your head. It's your mom's fault.
Seriously this guy acts like he deserves a medal for admitting he was shitty to Hyesung sometimes because he reminded him of his mom.
Protect Hyesung. Believe Hyesung. His trauma and belief system that drove the series exists because of this man.
Uhm if i remember didnt hye sung ran away because he was scared that his father would lend him to his clients (sexual deals) like what the father did to his mother. And the mother ran away because of that?
