My first love was strangely my friend's mother, Umi. When Noguchi visited his friend's house, he fell deeply for Umi, who was kind and beautiful. But she was his friend's mother—romance was impossible from the start. Still, he couldn't forget her, suffering silently with an unrequited love. If it's never going to happen anyway, nothing matters anymore. Driven by that despair, he crosses a point of no return. Losing all reason, consumed by passion, he aggressively pursues Umi. With each step forward, painful longing and pure desire intertwine, leading to an emotionally crushing climax.
