Noticing the growing attraction between Junichi and Kaoru, Masayoshi and Keiko decide to set the two up together by making them meet at the infirmary. There, Junichi tries to ask Kaoru out on a date on Christmas Eve, but to his surprise she has already planned to go out with him. On Christmas Eve, Kaoru decides to bring Junichi to the top of the new Port Tower despite his fear of heights. As they watch the snow fall, Kaoru confesses her love to Junichi, admitting she wants them to be closer. He in turn admits he loves her as well, that he wants to be with her forever, and they kiss. When Kaoru misses the last bus home, Junichi invites Kaoru to his home to stay for the night where both of them sleep together. Ever since, Junichi and Kaoru have become a loving couple.

Junichi and Kaoru are picked up by a passing truck who's driver sends them to a nearby hot spring inn with a bus stop. As they both start to argue over who's fault for missing the bus, the truck driver comments and gives some advice for the couple. Arriving at the inn, both of them realize the inn looks haunted and with only both of them the only customers, Kaoru is scared of being alone that she asks Junichi to accompany her even at the baths. After having a meal and heading to bed, Kaoru confess to Junichi that she set up this trip as she wants to know where their relationship is heading but Junichi has fallen asleep. The next morning, Junichi learns he left his coin purse at the bus stop, leaving Kaoru to use almost all her money to pay for the inn bill. Both of them argue again with Kaoru blaming Junichi for being careless and him blaming her for on always buying limited-edition snacks, which both of them refuse to talk with each other to the bus stop.
