Three orphaned sisters learning to live together in a house that still smells like their father. The show does not dramatize their grief, does not make it beautiful. It watches them eat breakfast in silence, fold laundry, argue about rent, and slowly understand that staying in the house means choosing each other every single day. This is what family actually costs when nobody else is coming to help.

Three sisters live together in one house in Monzen-Nakacho, a district of Koto in Tokyo's Shitamachi area. Their mother died when they were small, and their father passed away a year ago, leaving the sisters alone as the new inheritors of the Watanuki home. Their everyday lives bring happy, sad and special moments alike, and each one tests their bond as a family. The sisters are played by three VTubers in this warm slice-of-life TV series.
