He holds the weaknesses of the part-time girls at a retro Showa-era coffee shop... a new employee! A job-hunting student who comes to the shop! He eats them one after another for days on end!! Unable to resist the escalating demands, he becomes submissive! "Erotic photo-taking", "serving customers with a remote vibrator", "the humiliation of having a vibrator inserted", etc. The worst three days in history, he is forced to offer his prey in the shop while it is open!!
