Johira ni hibiku (E02)

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. (Crunchyroll)
