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...?!
It's not that I have anything 
against you, Yukimura-senpai...
...لا أملك أيّ شيءٍ ضدّك يا يوكيمورا-سينباي
Ist jetzt nichts Persönliches
gegen dich, Yukimura …
No es que tenga algo contra ti…
No es que tenga algo contra ti…
Ce n’est pas à cause de toi
que je dis non,
Non è che io abbia 
qualcosa contro di te, Yukimura-senpai...
Não é que eu tenha algo
contra você, Yukimura-senpai...
Юкимура, я ничего не имею 
против тебя, но...
