Procella's Yoru Nagatsuki and You Hazuki are childhood friends whose families have known each other for generations. Their personalities, preferences, strengths, and weaknesses are opposites, leading them to sometimes drift apart. However, as they continue to work under Procella, the two of them are true partners. They've spent most of their lives together. They can tell each other things too difficult to say to others. And because of that relationship, they sometimes clash... This is the, in a sense, same old story of an argument they have during a dance lesson while preparing for the Full Moon Festival.
To be honest, when I see Arata glowing, 
it makes me want to work even harder.
بصراحة، عندما أرى أراتا يتألّق، يجعلني
هذا أرغب في مضاعفة جهودي أكثر
Wenn ich Aratas herausragendes Talent sehe,
dann möchte ich sogar erst recht besser werden.
Si soy sincero,
cuando veo brillar a Arata,
Si soy sincero,
cuando veo brillar a Arata,
Parfois, voir Arata réussir
me laisse un arrière-goût amer.
Se devo dirla tutta, quando vedo Arata brillare,
mi viene voglia di impegnarmi ancora di più.
Sendo sincero, quando
vejo o Arata brilhando,
Если честно, мне хочется работать 
ещё упорнее, когда вижу запал Араты.
