It's a fantasy revenge drama about a woman who witnesses the affair between her best friend and her husband, and is murdered by them, she goes back in time to change her future and seek revenge.

This kdrama is also based on webtoon. (This has became new trend), but as per webtoon readers, makers have done some changes.

You get invested in the drama from 1st scene.

Story progresses with ample twists & turns, though we already know where it is heading.

Casting of Park Min-young as FL and Lee Yi-kyung as main villain is perfect. Specially Lee Yi-kyung is not only good in his villainous acts but he was equally good in comedy scenes. Park Min-young does what she is famous for. Her acting is perfect.

Na In-woo has wooden face but he is ok as lead as his only duty is to support FL. Good enough romantic scenes between leads.

1st female villain, is good in dramatic scenes but she screamed a lot, which was annoying.

In later episodes they bring another female vamp, which is not needed, she just increases the screen time.

It's a soap opera type kdrama, good watch for kdrama lovers.

Supporting cast is good. Drama ends with predictable happy ending. I enjoyed watching it.
