Intrafamily sexual harassment is an unresolved issue surprisingly many people face. Its severity feels like a shocking incident, and due to the lack of courage to confide in others, it remains completely hidden on the surface. Yua is one such person, carrying deep inner conflict.

Upon learning the truth, her older brother doesn't respond with mere sympathy, but seriously takes on the challenge of resolving his sister's suffering. His attitude symbolizes a bond far deeper than a simple sibling relationship.
