What's the worst thing that can happen if you write a romantic/melodramatic drama? That the main cast has absolutely no chemistry.
This is what happened here. Unfortunately the main characters were not interesting as separate persons and their relationship had the stupidest problems. To the point in which, there isn't any conflict as to why they can't be together.
So she had an affair with an about to be married man, that turns out was a step-brother of our leading man. Too bad, the affair lasted a summer, and she, unknowingly of his demise, decides she is never going to love again.
But honestly ,her past relationship...like I don't see how it could have haunted her to the point of making her deny any present happiness.

The rest of the characters are no better, the other relationships go from totally toxic, to downright sad, to goofy. But I never got any real interest in any of them.

The only part that made me go back to watch was the fashion related plot, but this was ,at best, 5 mins per episode. Until the last episode. And it was presented as if someone, who was never heard of the fashion world, did a fashion drama. It doesn't really feel real.

If anyone else is here for Sehun, as an EXO-L, I am satisfied by his participation, but it was kept to the minimum. Which is sad because I feel his relationship with the company intern was one of the funniest. But maybe this was because the writers didn't get time to ruin it like most of the drama's relationships
