Teach You a Lesson

It's highly recommended to watch this series, besides the many things that can be learned from this film, the fighting action is also really cool, in each episode I don't feel bored, in fact I feel like time flies really fast even though it's running normally, the actors are actually none that I know as someone who often watches K-dramas, I feel like the actors are fresh to be brought up in other K-dramas because they have a lot of potential, and I also really like the characters because they have a backstory, especially the saddest one is Na Hwa-Jin in my opinion
