The drama is inspired by the French Novel called the Dangerous Liason. If you ever heard about it, you will probably get the gist of the whole story. I find the story is gentler and lighter than the original dark story (the original is a tragedy but this one still give you a happy end at least). The story centered on the 3 childhood friend who starts the love game as revenge. But the love game actually brings ford the tragedy of the past as well as changing their whole life and relationship with each other.

This drama may be not for everyone. The characters are not meant to be like. But I find if people are complaining about the selfish characters of this drama, that means all the actors and actresses are doing a great job in portraying them. I find the vulnerability and the selfishness of the main four characters are humane. I mean no one is perfect, everyone has their own desire and selfishness but you can see that they grow up by the end of the series.
