[The private sex life of a boyfriend and girlfriend, leisurely cooking and then making love at home] "How long have we been dating?" This kind of private, self-made record that they don't want others to see, shopping together at the supermarket, drinking and being affectionate, playing around while taking a bath, makes people feel "what a day this is, I want to cherish it, and it might even remind me of things I wouldn't normally think about." This is a very erotic adult film.
