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...?!
even if I keep my glasses on, 
we should avoid a collision of noses.
.حتى وإن أبقيتُ على نظّاراتي فسنتفادى اصطدام أنفينا
kann ich die Brille auflassen
und unsere Nasen kollidieren nicht.
aunque me deje los lentes,
mi nariz no colisionará con la tuya.
aunque me deje las gafas,
nuestras narices no colisionarán.
même en gardant mes lunettes,
anche indossando gli occhiali,
dovremmo evitare di scontrarci col naso.
mesmo se eu ficar de óculos,
evitaremos a colisão dos nossos narizes.
то мы не заденем друг друга носами, 
даже если я останусь в очках.
