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.
Above all, they're teacher and student.

Un profesor y una estudiante
no pueden estar juntos.
Un profesor y una estudiante
no pueden salir.
Et puis entre un prof et une élève,

E poi, un professore non può
mettersi con una studentessa.
Além disso, aluno com 
professor não tem condição.
Вдобавок, они — учитель и ученица!
