I'm so sorry, but this movie ruined the original webtoon story. In the webtoon, Si Eun's character developed not only from his way of thinking but also from his martial arts side, but in the movie he was made to remain reckless until the end. I don't know, if I were the original author I would be disappointed if the story deviated a lot from the original story. Maybe the intention was to develop their own story, but it deviated too far. Please don't remake a webtoon if the story is changed this far, it's a shame because the actors are good, their acting is also cool.
