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...?!
But, what do you mean to 
do about this mood value?
لكن ما الذي تنوين فعله بخصوص قيمة المزاج هذه؟
Aber wie willst du den
Stimmungswert wieder erhöhen?
Pero ¿y el valor de ambiente?
Pero ¿y el valor del ambiente?
Mais qu’est-ce qu’on fait,
pour l’atmosphère ?
Ma cosa intendi fare per questo valore di atmosfera?
Mas, com essa ausência de clima,
o que quer que eu faça?!
Но что делать с низким 
индексом атмосферы?
