I'm grading this halfway of as someone who was the target audience 20 years ago and as who I am now. Body swapping is extremely intriguing especially as it happens here between a conventionally extremely attractive man and a bullied chubby friendless boy. But I could not care less about fashion and K-pop aspects of the story.

Pretty amusing little Korean anime with a supernatural twist, almost reminded me a touch of Ranma 1/2 with the body swapping twist and the fact that everyone at the school appears inclined to fight in these boxing / martial arts battles at the drop of a hat. The bullying scenes get a bit tedious and nonstop after a while (and so over the top it becomes almost hard to believe even in an animated world) and some side characters are underdeveloped but the main premise is amusing enough.
