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.
I know that I don't know 
her as well as you do,
،أعلم أنّني لا أعرفها جيّدا كما تعرفينها
Verglichen mit dir weiß ich
wohl fast nichts über sie.
Comparado contigo, es verdad
que aún no sé nada de ella,
Comparado contigo,
es verdad que aún no sé nada de ella,
Comparé à toi,
So di non conoscerla bene quanto te,
Comparado a você, talvez eu
não saiba nada sobre ela,
Я понимаю, что знаю Цукасу
далеко не так хорошо, как ты.
