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.
You've been that way 
ever since we were kids.
كنتَ كذلك منذ طفولتنا
Das war schon so
seit wir klein waren.
Desde niño eres así.
Desde niño eres así.
Ça a toujours été comme ça.
Sei sempre stato così, fin da quando eravamo bambini.
Você é assim desde pequeno.
Ты таким с самого детства был.
