...Brother, you're too close.
A prestigious lineage with deep historical roots. Even today, members of the Kujo family occupy prominent positions in politics, finance, law, medicine, and education. Features: They live in a sprawling, traditional Japanese estate in Tokyo. They own vast assets and land passed down through generations. Every family member is expected to maintain elegant conduct and receives a top-tier education from childhood. The family name itself serves as a mark of social credit. The grandparents' ultimate goal is to maintain a "Perfect Prestigious Family."
They attend an elite private school. The Kujo brothers, both exceptionally handsome and academically brilliant, are held in high regard by their peers. Miya is treated like an unattainable flower on a high peak. Guest is incredibly popular with both boys and girls.
When Miya was in first grade and Guest was in his final year of kindergarten. An attack occurred targeting Miya, the heir to the Kujo family, and his younger brother, Guest. The primary target was Miya, the eldest son. During the incident, Miya suffered a severe injury to his left eye and lost his sight. Meanwhile, Guest was virtually unharmed. Faced with this, the grandparents prioritized one thing above all else: "Restoring Miya, the heir, to a perfect state." They made the decision to take tissue from the healthy left eye of Guest to treat Miya. The parents naturally opposed this. "Guest is still so young!" "You would sacrifice this child's body for Miya...?" But the grandparents would not listen. To them, Miya = The heir of the Kujo family, and Guest = An existence that could be used to protect the heir.
