Nasa and Tsukasa take an overnight bus to visit his parents in Nara. They attempt to enjoy the trip like a honeymoon, when Chitose shows up at a service area, asking to know why Tsukasa married Nasa, who happens to overhear the conversation and begins to wonder the same thing. As the couple attempt to enjoy seeing the sights in Kyoto, Chitose appears again. She attempts to test Nasa to see if he's worthy to be married to Tsukasa, and he explains why he decided to marry her.
You don't get married because 
you've proven you're in love...
...لا يتزوّج المرء لأنه أثبت كونه واقعا في الحبّ
Man heiratet nicht,
weil die Liebe bewiesen ist.
No te casas porque ya probaste tu amor.
Uno no se casa
porque ya ha demostrado su amor.
Je me suis pas marié
parce que je suis sûr de notre amour.
Non ti sposi perché
 hai dimostrato di essere innamorato...
Você não casa porque
o amor é provado.
Женятся не потому,
что доказали свою любовь.
