The whole story is a mess

I watched this because I love Yang Hyeji. But, I assure you that this review isn't bias. I regret watching this because the story is a mess. There are a lot of events that are not revealed. How come Mina seems to have a happy ending while doing bad things and being selfish? She is not the main character of this story. She has been bad and Jayeon deserves better. The male lead was right. Why didn't she tell the truth from the beginning. That would have stopped the mess from the beginning. This drama teaches selfishness which isn't a good thing. Sorry to say this.
