all youth movies are about sex, love, friendship, etc. this one is no exception. it even pushes these elements to limit. the arrangement of casts is interesting itself: two youths fight for a woman in early 30s! some audiences argued that the woman was not attractive to the youth, but i think it is the intention of the director. they were not attracted by her beauty, they were bonded together by curiousity and fun. besides, the woman's figure was associated with the secret disclosed by the end of the movie. its heavily used voice-over demonstrates how to use this technique intelligently. i bought the r1 dvd with rich features including one interesting short movie by the director.
