Ibarada suggests that one of the greatest factors in the base conditions of romantic love is "whether or not you want to kiss the person," so Yukimura decides to try to kiss Himuro. However, Himuro doesn't like the idea of a kiss where the exact angle is measured with a protractor.  When Himuro realizes that if the mood were more like it had been in the Ferris wheel, she might not mind a kiss, she and Yukimura create an equation to numerically define "mood value." In what location might the "mood value" be highest? And will the two of them be able to kiss...?!
Therefore I'll have the same as Kanade-chan, 
the back of my hand.
.لهذا، سأفعل نفس ما فعلته كانادي، على خلفيّة يدي
Deshalb bitte wie bei Kanade
ein Küsschen auf die Hand.
Entonces, que sea la mano,
como con Kanade.
Entonces, que sea la mano,
como con Kanade.
Fais comme Yukimura avec Kanade,
sur la main.
Quindi scelgo come Kanade-chan il dorso della mano.
Então, pode ser na minha mão,
igual a Kanade-chan.
Поэтому предлагаю поцеловать мою руку.
