When Mugi and Yuu miss the last train home after a late night out, a friendly restaurant proprietor, Tetsu-san, invites them in from the cold. Impressed by Mugi?s passion for cooking, Tetsu offers him a job . . . which is how Mugi comes to meet the gorgeous eighteen-year-old Aoi-san, a wandering artist (and kissing machine) who is deeply in love with Tetsu. Unfortunately, Tetsu isn?t interested, but hey . . . a kissing machine?s gotta kiss somebody, right? It turns out that nobody is safe from Aoi-san?s smooches, not Tetsu, not Mugi . . . not even the unsuspecting Yuu-chan!
