Not worth your time

If I had to resume this kdrama in one sentence would be: Why?

Why the ml loves the fl?
Why the fl doesn't have a personality?
Why the villain hates so much Mi rae and wants to destroy her?

Theres no answer to these questions. Drama with poor writing and a boring plot. I wasted my time.
They could have done so much better with the subject, but decided to take the easy route instead of going in dept about beauty standarts, plastic surgery, bullying, divorce and domestic violence. They missed the mark big time.
