Shouzou and Ine, an old married couple, are known to everyone as a pair of lovebirds. One day, they wake up to find they look like their younger selves! When Mino, their granddaughter, sees them, she's shocked by their transformation, and she's not alone!
Momentum carried me in here 
before I knew it...
تركتُ زخم تلك اللّحظة يتغلّب
...عليّ قبل أن أدرك حتّى
Im Eifer des Gefechts
bin ich reingekommen …!
Acepté la invitación sin pensar.
He aceptado la invitación sin pensar.
Je suis entré sans me faire prier !
Sono entrato senza pensarci!
Me deixei levar e acabei
entrando sem perceber...
Не смог отказаться…
