Hanagaki Takemichi is a worthless part-time worker who's down in the dumps. One day, he learns that his girlfriend from junior high school, Tachibana Hinata, was killed from being a victim of the conflict between the Tokyo Manji Gang. Takemichi is shocked by the sudden news but goes about his daily life when he is suddenly pushed off the station platform onto the railroad tracks. He is prepared to die as he sees the train coming right for him, but the next thing he knows, he's reliving his life from 12 years ago.
Thinking back, my second year in 
middle school was when I peaked.
.بالتفكير في الأمر، كانت السنة الثانية من الإعدادية أفضل أوقاتي
Rückblickend war meine Zeit
als Achtklässler meine Blütezeit.
En retrospectiva, mi segundo año
de secundaria fue el mejor de mi vida.
Si lo pienso, mi segundo año
de secundaria fue el mejor de mi vida.
Quand j’y repense,
Ripensandoci ora, il secondo anno delle medie
è stato il periodo migliore della mia vita.
Pensando bem, meu auge foi
no segundo ano do ginásio.
Если подумать, мои лучшие
дни были в восьмом классе.
