Yuki broke up with his mother when he was five years old, and grew up without knowing his mother's love. The image of her mother that she vaguely remembers was dignified, kind, and beautiful. For Yuki, the only hope to live on is the memories of the few days she spent with her mother when she was young. And when Yuki was 25 years old, she received a letter from her mother saying that she wanted to meet him for the first time in 20 years. She went to the promised hot spring resort without Yuki realizing that her feelings for her mother were her romantic feelings.
