Here's also the thing

What's so sad is, Jinjoo was doing the right thing bu trying to break it off with Doyeon. She apologized for the situation she put Doyeon but ita best to go their own ways and Doyeon is still young and will find someone better suited for her. A very clean way to break up with someone.

But Doyeons crazy ass just couldn't accept that... damn. I also believe Jinjoo isn't going to stay with Her manipulative husband but was also using it as an excuse to break up with Doyeon.

Maaaan this is sad. Doyeon really severed Jinjoo's only for of self, outside of her messed up husband
Damn...what a mess
