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...?!
I-It's not my fault the mood value dropped!
!لـ-لست السبب في انخفاض المزاج
W-War doch nicht meine Schuld,
dass die Stimmung so mies war!
¡No es mi culpa que el valor
del ambiente bajara!
No es mi culpa que el valor
del ambiente bajara.
C’est pas ma faute
si l’atmosphère est tombée.
N-Non è colpa mia se il valore di atmosfera è calato!
N-Não é minha culpa que
o valor do clima tenha caído!
Я н-не виноват, 
что индекс атмосферы упал!
