This work tries to replicate one of the most popular clichés of Japanese works: the wimp suddenly and magically becomes the coolest man in school, and everyone wants to be friends with him, and all the girls want to f***k with him. But the Korean title does it, probably in a very typical form for their titles: too many bright special effects against the background of too sharp and superficial actions of the characters. I think that this is purely for fans of Korean anime.
The story itself, however, is well shown.
