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...?!
Sorry to interrupt. I'd like to lock 
up the roof before it gets dark.
آسف على المقاطعة. أودّ إقفال
 .السطح قبل حلول الظلام
Ich störe nur ungern, aber ich
schließ hier zu, wenn es dunkel wird.
Disculpen. Quisiera cerrar
antes de que anochezca.
Disculpad. Me gustaría cerrar
antes de que anochezca.
Excusez-moi !
Scusate per l'interruzione.
Vorrei chiudere a chiave il tetto prima che si faccia buio.
Desculpe interromper. Eu gostaria
de fechar aqui antes de escurecer.
Извините, что прерываю. Нужно закрыть 
дверь на крышу, пока не стемнело.
