I just don't know, what the movie was supposed to tell us. That the people, who go to love hotel, have sex there? Actually the movie didn't catch enough of my attention, so I just loosely followed. The first half or even more is about different people renting the room in the said love hotel and having sex in there, and the staff was permanently listening to them. Maybe it was involuntary, they had some ventilation going to the staff room and it served almost as a speaker... But even so they didn't see it coming, that two guests (room teacher and a high school student girl) commited suicide. After that and the death of the father, who was the first owner, the young owner closes the love hotel and leaves for somewhere, presumably Tokyo. And bevore leaving she also has sex in the same room with some guy, whom she liked since high school...
That's it. I don't understand why it was filmed in the first place. The acting was alright, considering the script. Story is more or less none-existent. Music was okayish. If someone wanted to make an erotic film, the movie doesn't show anything, despite many moments with people having sex, there is nothing erotic or sexy. Also I don't understand why Matsuyama Kenichi and Yasuda Ken would play in that movie...
