I am a fan of the reincarnation/returning to the past genre? Something like that. I would definitely recommend this drama as a drama lover. The story raised may be quite marketable. But the drama execution gets maximum results. This drama is very fresh, funny, lots of action and fighting scenes, very strong friendship, regret, apology at the end. Apart from the story, I am very satisfied with the acting of all the actors, both main and side actors. I even cried at certain times because they delivered the right emotions in each scene. However, there are still several questions in my mind regarding the continuation of the story of the side characters in this drama. I hope there will be a continuation season 2.
