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.
They let me do as I liked, and I'm 
truly grateful to them for that.
سمحا لي بفعل ما أشاء، وأنا ممتنّ
لهما على ذلك حقّاً
Ich bin ihnen sehr dankbar,
dass sie mich haben machen lassen.
e sono molto grato del fatto
Eles deixaram eu fazer o que eu quisesse
e eu sou muito grato a eles por isso.
