10nen Zakura talks about leaving school and not seeing the people you love anymore, and asks that they meet again in 10 years. The MV starts, before we get any music, with Maeda reading a letter while stood on a wall, and we're informed it's 2019. We also have Itano, Kojima and Watanabe talking about the past. Maeda's joined by Yuko, who's pregnant, and they talk a bit as well. We then get to the music in 2009, with the girls together in school, messing around on the bus, in the classroom, Mai and Minegishi sharing pringles etc. We then get them going home on the school bus together for the last time. Initially their all still messing about, but things calm down as the girls start leaving the bus in pairs, until it's just Maeda and Takahashi, with Atsuko asleep on Minami's shoulder. Maeda wakes alone, with the letter in her hand and turns to see Takahashi behind the bus as it leaves. With the end of the music we return to 2019, Atsuko and Yuko discuss Takahashi, as the 3 girls notice either them or some other girls, it's not terribly clear. we get a brief shot of Takahshi, who seems to be watching her, before Atsuko and Yuko walk together for a bit, and Yuko says she's naming the child Sakura.
The B-side talks about being handed flowers at your graduation by your first love, and how for now the people just want things to stay the same.
This is the last single to feature Oshima Mai, as between here and the next single she graduated.
