Yuna Satou and Emma Satou work at the same part-time job, share the same last name, and come from similar family backgrounds, but other than that, they have nothing in common. Due to a strange turn of events, they end up living together. They fight sometimes, but it is precisely because they are opposites that they can stay together. A new generation's story about girls who live freely! (Source: Homesha, translated)
