My mother divorced due to her husband's domestic violence and raised my daughter Momoka alone. Momoka, who witnessed her father's domestic violence, became phobic of men and could only love women. And that love gradually turned towards my mother, Yuu, who had raised her with great effort. One day, Momoka invites her mother to a hot spring trip. The ostensible reason is to express her gratitude to her mother, but in reality, it was to confess her love to her mother.
