Yes there is a lot, like a lot of sex scenes, but I don't this it was to much or to explicit sex was part of the plot there's more about the movie than sex. This about Love, different kids of love, there is friendship, true love (no matter how it started)and the extremely obsessed one this is what I think the movie is really about. The acting is flawless, great job, every single character was well played and which I bet it wasn't easy to play. The music is outstanding traditional Korean music that helped no only to understand the scene but also to understand the characters feelings. If you're over 18 (just saying), should watch it, and see there is more deep than just just sex.
