Tung baan tung hok

So, as I watched this, I was trying to figure out how it started. It jumps right in the middle with three high school girls doing the usual high school thing, taking selfies, fawning over a jock, the usual peer pressure but two of the girls are what I assume is high end prostitutes. They befriend the third girl out of osmosis. Somewhere in this mix is some confusion to the story line because most Asian films have convoluted stories where either the hero dies most often and the hero doesn't get the girl in the end or they just don't have the atypical happy ending. These girls are problematic. While they all seek boyfriends, they can't seem to reconcile the fact that they are hookers and nobody will find out. And also, I don't know if they are minors but the sex that they are having with older men seems to push the boundaries with having sex with minors. This is just glossed over without a mention. The girls talk about having sex with older men but not about the legality of it which is probably right because their world is limited to selfies and the latest fashion. In the end, one of the girl takes a boyfriend from one of the other girl and that ends disastrously. They make amends and they frolic along the shoreline with naked abandon. Yeah, see, that don't make much sense.
