I like how everyone ignores what this drama is about and just criticizes the female lead.
Her own family ignored her cause her mother wanted it that way. Her so called senpai trapped her in a Stockholm Syndrome and took advantage of her.
No one cared to help her out and she finally started to be strong enough to break free herself.
It's what all abuse victims suffer from, the feeling that they're not enough and no one gives a $hit about them.
I doubt any k-drama would even gave a story like this cause they're all virgins and the hero is their first love.
From what I've seen in reactions about this drama, Koreans are right. No one wants to see the reality of someone who tried to escape an abusive relationship. Really a pity...
