Ohana Matsumae, a 16-year-old girl from Tokyo, is sent to live with her estranged grandmother, Sui Shijima, after her mother elopes with her boyfriend. Sui runs Kissuiso, a traditional hot spring inn in the countryside. Ohana, accustomed to city life, struggles to adapt to the rural setting and the strict, demanding environment of the inn. Her grandmother is a no-nonsense, hardworking woman who expects Ohana to contribute to the inn’s operations, leading to frequent clashes between them.

At Kissuiso, Ohana meets a variety of characters who shape her experiences. Nako Oshimizu, a shy and diligent coworker, becomes one of Ohana’s closest friends, while Minko Tsurugi, a talented cook, initially resents Ohana’s presence due to her own insecurities and aspirations. Tomoe Wajima, the cheerful and experienced head waitress, provides guidance, and Tohru Miyagishi, a young chef with a carefree attitude, becomes a source of both support and romantic tension for Ohana. The staff and guests of Kissuiso collectively create a vibrant, interconnected community that challenges and nurtures Ohana as she navigates her new life.

The narrative explores Ohana’s growth as she learns the value of hard work, responsibility, and perseverance. Her journey is marked by both triumphs and setbacks, as she confronts personal insecurities, familial tensions, and the complexities of relationships. The inn itself serves as a central backdrop, with its traditions, challenges, and seasonal rhythms reflecting the broader themes of change and continuity. As Ohana becomes more integrated into the inn’s operations, she begins to understand her grandmother’s dedication and the importance of preserving Kissuiso’s legacy.

Throughout the series, Ohana’s relationships with her mother and grandmother are pivotal.
