The story begins with Miyu, who is called by her father, Oyaji-san, to talk about something important. She recalls that Oyaji-san had passed away, a fact that still feels distant to her. He had been raising a child alone after separating from Okaa-san, and now that he's gone, the child is left without a family. Miyu, touched by the situation and wanting a brother, agrees to take the child in. The child, Yuuya-kun, is introduced to Miyu as her new sibling, and the three of them start to bond.
As the days go by, the relationship between Miyu and Yuuya-kun deepens. They spend time together, sharing moments of fun and quiet understanding. The family dynamic is still adjusting, but the promise of a new beginning is in the air. However, as they grow closer, a new kind of connection begins to form—something more intimate, more personal.
One evening, after a long day, Miyu and Yuuya-kun find themselves in a moment of shared comfort and vulnerability. The tension between them builds, and as they both let their guard down, a gentle seduction takes place. The setting is warm and familiar, like the home they now share, and the emotional arc shifts from a sense of family to a deeper, more personal bond.
As they continue to spend time together, the moments of intimacy become more frequent, more intense. The connection between Miyu and Yuuya-kun is no longer just siblinghood—it's something more. Each shared moment adds to the growing understanding between them, and the promise of a new kind of relationship is slowly taking shape. The journey from family to something more personal is unfolding, and the warmth of their bond continues to grow stronger with every passing day.
