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.
And that was the only 
time I had a girlfriend.
.وكان الوقت الوحيد الذي كانت لي خليلة فيه
Es war die einzige Zeit,
zu der ich eine Freundin hatte.
Y fue cuando tuve novia.
Y fue cuando tuve novia.
et j’avais une meuf,
la seule de ma vie.
Ed è stato l'unico periodo in cui ho avuto una ragazza.
E foi a única vez que
eu tive uma namorada.
И только тогда у меня была девушка.
