Koguma visits Reiko at her home, and the two have dinner together. Reiko recounts the story of how she took a job at the Mountain Hut Kikuya over the summer as a means to pursue her own dream, something which proved to be more difficult than expected.

With the colder weather taking its toll, Shii comes up with a way to provide both Koguma and Reiko with a little relief. But when the temperature dips even lower, the pair are faced with adopting measures for their Cubs that they are reluctant to accept.

The girls pack up and depart on a road trip to Kyushu, the most distant location their Cubs will take them, in order to shake off their winter doldrums and embrace spring. Along the way, Shii finds what she needs to help her continue her café project.
