It's comedy, it's drama, and it's romance. A lot of sexual references, a lot of sex scenes. The Nudity is severe. Although it's like a soft porn, but there is a lot of funny lines/scenes. In Europe/America, romance is derived from sex but in Asia, it's the other way around (in most cases). But this movie follows the former- "sex first, romance after", which is very unusual in Asian movies/TV series. People with western background can hardly understand the humor in Asian movies but those funny points are very funny and entertaining in Asia. That's cultural difference, and you can't say it's a bad movie because you don't understand their culture and background.
