This a simple / short version of the manhwa. I haven't read the novel, but I've read the manhwa. The manhwa were more comokicated and very long. But I like the manhwa.
The movie have the same plot but a lot of details are missing or edited.

Maybe it won't leave a great impression afterwards. But this is good enough for entertainment. No violence, not much misunderstanding, not overly tragic story line.

I gave the music rate only 1 because there's no OST that I like from this movie.
