The original plot was pretty good but it was done terribly and just got ruined.
The FL should have more backbone, like she's an accomplished woman and she gets herself get treated like dirt.
Even her 'standing up for herself' was mushy and only happened because she wanted to sleep with the ML. Who by the way is a HUGE RED FLAG. There is no excuse, he raped his old girlfriend and since I don't want to give anymore spoilers ill just say that the show was predictable and crudely made.

So if you watch it just turn off your brain and try to enjoy.

By the way I love Dori but honestly I don't think that his acting can save this drama.
