Satsuki had rejected her mother's wishes for her to inherit the inn, leaving her mother and brother to run it as she left for her own life.

Due to her boyfriend writing her name on his papers, the debt he falls into forces Satsuki to make a moonlight escape from her normal life. As a result, Ohana is sent to her grandmother's inn due to the not-so-motherly nature of Satsuki. She has a surprisingly infamous reputation at the Inn, being the first topic at hand when staff members talk to Ohana for the first time.
