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.
Something like this belongs in 
a treasure box, not a trash can!
Das ist kein Müllsack mehr,
¡Algo así debe estar en un cofre,
no en la basura!
¡Algo así debe estar en un cofre,
no en la basura!
Ce n’est pas un sac poubelle,
mais un coffre au trésor !
Una cosa del genere deve essere tenuta
in uno scrigno, non in un cestino dei rifiuti!
Devia estar num baú de 
tesouro, não numa lata de lixo!
Такое нужно бережно хранить, 
а не выкидывать в мусор!
