Upon finding an old raincoat in her closet, Kaede recalls her middle school friend, Yuuka, who was often concerned about her climbing mountains. When Yuuka got upset with her after she ended up spraining her leg, Kaede came to realise she had never taken Yuuka's advice to heart and apologised, after which they bought a raincoat together. Feeling nostalgic, Kaede rings up Yuuka and the two go out shopping together.
