During Yuzu's daily routine of stalking through her sister, Akane's trash, Guri suddenly appears and the two girls begin taking love consultations at school. Seiji and Akane reluctantly agree to help look for coupling candidates and soon the group thinks they have found a pair of ideal targets. However, things get much more complicated when no one can agree if the intended couple really share each other's feelings. In the midst of all this Yuzu and Guri scheme an elaborate plan to prove their instincts are right.
Sensei, while even I agree that this is 
a weird setting for a confession of love,

si se confiesa aquí,
Monsieur, ce n’est pas vraiment
le moment idéal pour une déclaration,
Professore, anch'io credo che questa sia
una situazione strana per una dichiarazione d'amore
Professor, eu também não acho ideal 
se declarar numa situação dessas,
Учитель, я понимаю, что это
нелепая ситуация для признания в любви,
