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!
To think I'd end up alone like this 
with someone everyone admires!
لا أصدّق أنّ المطاف انتهي بي هكذا
!وحدي مع شخص يحبّه الجميع
Dass ich mit so einer Ikone
mal nur zu zweit sein würde …!
Che ci fa uno come me
insieme a una ragazza ammirata da tutti?!
E pensar que eu acabaria ficando sozinho
com alguém admirado por todo mundo!
Я и мечтать не мог, что останусь
наедине с такой девушкой!
