During their first night sharing a room, Yuzu had her first kiss stolen by her step sister. Since then she can't get Mei off her mind, while Mei herself goes on as if nothing happened. Meanwhile, Mei's Grandfather, the chairman of Aihara Academy, takes Mei back to his mansion. Unable to forget the sad expression on Mei's face when they kissed, Yuzu heads to the mansion to confirm Mei's true feelings, but...?!
A child who's never kissed someone 
before shouldn't act like she understands.
Kinder, die noch nie geküsst haben,
sollten sich ihre Ratschläge sparen.
Una mocosa que no ha besado a nadie
no es quién para hablar.
Una mocosa que no ha besado a nadie
no es quién para hablar.
Je n’ai pas de leçons à recevoir
d’une gamine qui découvre les baisers.
Una bambina che nemmeno ha mai dato un bacio
Uma criança que nunca beijou
não devia agir como se soubesse.
Дети, которые никогда не знали поцелуя,
не должны говорить так, будто знают.
