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.
And make herself a happy family. 
That's what I hope, anyway.
وتبني عائلة سعيدة لنفسها. هذا 
ما آمله على أيّ حال
Ich hoffe, sie gründet
eine glückliche Familie.
y tendrá una familia feliz.
Eso es lo que espero.
y tendrá una familia feliz.
Eso es lo que espero.
et un partenaire qui lui plaira.
e che si facesse una famiglia felice...
e que crie uma família feliz.
и заведёт счастливую семью.
