Sunyoung, Nana, and Sara were all women betrayed by the same man, Junseo, and now they come together to get revenge.
This story touches upon many important topics - one of them being cheating. Sunyoung is in a relationship with Junseo, who already has a wife, except she doesn't know this so when it's revealed she's called a homewrecker. However, she's a victim.
Nana is in the same place as Sunyoung. She's called a homewrecker for being in a relationship with Junseo even though she never knew that he was married. She, too, is a victim.
Sara, on the other hand, is the wife. She is Junseo's wife. When people find out that her husband has been messing around with other women, Sara is blamed for not "keeping him in control." However that isn't her job. She is also a victim.
All three of these have one thing in common- The fact that society decided to put the blame on the women while it was the man's fault.
I also love how the author gave the characters development, even some of the side characters. And I guarantee you that you will not be disappointed with the ending. Junseo got what he deserved and the girls got their revenge.
While there is a romance tag, there's very little romance. At the end of the story, the main girls end up being best friends but aren't in any romantical relationships of their own. Unless you count Yoon who was still pestering Sunyoung because he had a crush on her but then again Sunyoung had no interest towards him haha.
Overall, I would definitely recommend this story if you want something that shows realism and problems that people face in the real world.
