It's at the end of Town Elementary's school year and our students are gearing up for the summer season. On the last day the students must make up for lost time by engaging in a school trip, upon returning, one of the students comes full-handed with a broken souvenir. While the summer for our characters starts, her friends, unfortunately had other plans to dwell in their own interest and leaving Pei to contemplate on hers. Will the lucky souvenir lead her back at square one or something more?
