Summer's Eternity
Tetsu goes to Karada's apartment to look for her and even talks with her himself, but he doesn't recognize her. The rest of the day, they go around town together to places Karada might be and end up in a hidden place where the source of the river's water is.

Living for the Day After Tomorrow
There are far worse things than having to deal with your ex-boyfriend's little sister or your older brother's ex-girlfriend. But that's something Karada Iokawa and Shoko Nogami have to learn the hard way when a magic wishing stone inexplicably grants Karada's wish to be older - and does it by stealing the years from Shoko! Now Shoko, who's already graduated and studied overseas, is Karada's age, just about to enter junior high school. Meanwhile Karada must suddenly face the real facts about what being grown up entails. And just to make a bizarre situation even more awkward, there's the issue of how to handle their existing romantic interests!
