Onuma Mihono works at a travel agency. After breaking up with her boyfriend of six years, someone she had been thinking about marriage with, she realizes she is already 30. Then, a man transfers into Mihono’s company. It is Ureshino Eisei, the “accomplice” with whom, despite both of them having lovers at the time, she had a physical relationship 10 years ago. Mihono is shaken when Eisei speaks to her with a cool expression, but she resolves to treat him normally. However, when they are alone together, Eisei whispers in the same sweet voice as back then. “Don’t you feel like we’re destined?” The pleasure and desire that revive with their reunion. And yet, even after 10 years, she still cannot grasp his true feelings. Am I the one he truly loves? Or am I just for fun? Even as adults, unable to break free, she sinks deeper into a secret relationship.
People gather at a split-level flat on a backstreet of Roppongi, Tokyo, men pay ¥20,000, women ¥1,000 and couples ¥5,000 apiece to spend the hours of midnight to 5 a.m. at a sex party. A moody Neet guy empties out his bank account for this night of pleasure, and a bespectacled college student who at first impresses as mousy and shy join the party. Presiding over this orgy are a jaded manager and bartender who explain and enforce three simple rules: Take showers prior to sex, use protection and respect the wishes of the women. Most dangerously, the Neet guy is falling quietly and hard for the student, who reveals herself as the horniest of all, while never quite breaking out of her shell.
