Horikawa Mitsuru, a high school student, works at Ryokushou with Itsuka. Seeing the two of them chatting happily together by the sink makes Nagomu feel a little jealous.
While Mitsuru works part-time at Rykoushou to help supplement her large family's finances, she's also actively making music. And her musical activities kick up some trouble.
I rely on her for everything. 
She's so responsible.
أعتمد عليها في كلّ شيء. إنّها صاحبة مسؤوليّة
Sie macht fast alles für uns.
Confío en ella para todo.
Es muy responsable.
Confío en ella para todo.
Es muy responsable.
Elle en fait beaucoup pour nous.
Se non ci fosse lei non saprei come fare...
È sempre così brava.
Estou tendo que me apoiar muito
na ajuda dela. Ela é tão responsável.
Без неё я как без рук.
