Well.

The writing sucked. It was like this was penned by a teenager using chat GPT. Very debut author YA fantasy. The plot was lazy and repetitive, with characters being wishy-washy and similar events being recycled. Editing wasn't much better, with scenes just cutting out in the middle of them and the characters continuing their conversations somewhere else. The dialogue was also fairly cringe, with lots of yelling to assert dominance and show power, like any good makjang should have LOL. Perhaps the webtoon was better, I wouldn't know.

But the soundtrack was fantastic, and the filming and acting were quite good. I wish there would have been a more consistent difference between Hyeon and Ak Hee's personalities, since at times it got difficult to tell them apart, but I still think Park Ji Hoon is amazing given his young age and newness to the world of acting. And I'll always applaud a production that can flawlessly and convincingly turn a single person into two, fighting scenes included and all.
