To be honest even though i know that fact, I'm not really irritated. In this manhwa every character have a flaw like every person. And if you think the perspective of other character you will realize that if they're the main character i will probably hate the person they also hate. Do you get what im saying??? My English and spelling skills are not really good....
In this manhwa you will see how human nature or cycle works.... It's too bad that this is happening in our world.
