This film seems to have been a cross between Romeo & Juliet and some of the most popular Yaoi Manga.
Our protagonist is a young reporter/editor who meets and falls for a popular model/painter/school-boy who is dealing with some childhood abandonment issues by being promiscuous.
Unfortunately there's a another school-boy in love with our promiscuous model who is ignored until a very foreseeable end comes about.
As with most Japanese films that I've seen, I'm not sure what's realistic and what is stylized. The plot is presented largely in flashback but attempts to maintain the element of mystery. Presenting scenes out of order and allowing the audience to fill in blanks in the back-story is a well-established way of engaging the audiences interest and to some degree it works here.
The actors were certainly attractive enough and the skin scenes were titillating but I would have enjoyed learning more about what was going on below those beautiful surfaces.
Also the production values were wildly uneven. Obviously great care and effort went into picking out some wonderful locations (particularly the pool and the aquarium themed restaurant) but the artwork that was supposedly done by the model/artist/schoolboy was barely refrigerator door quality.
Also the subtitling frequently suffered from white on white washout. The picture might have been better served by a black border with subtitles below.
Unfortunately by the film's conclusion I was still uncertain how much of what had been portrayed was poor film making or was poor cultural understanding on my part and the story wasn't strong enough to overcome these flaws.
I found that I didn't really care for these characters enough to really recommend this film.
