Komiya Nonoka and her father return to the town they left 7 years ago. The town has changed in a big way, there's a huge saucer floating above the lake.
Nonoka tries to figure out several confusing relationships she has with familiar girls in the town. She's not sure where she fits in after so much has changed.
Nonoka tries desperately to make friends with local girls during an orienteering trip, but some of them are treating her differently, as if they know something she doesn't.
Nonoka doesn't remember everything, but she does remember a promise she made to watch fireworks together. Now she wants to make things right with Yuzuki.
Nonoka goes to see Shione and tells her about her wish. Yuzuki and her brother Souta talk about their wishes too, as a bigger story is unfolding with each confession.
