Luna, an orphan adopted by the Johnson family, once had three doting older brothers and a happy home, but after their biological daughter Estella returned, Luna was reduced to a bullied stand-in. Heartbroken after being misunderstood and hurt over and over, Luna finally chose to volunteer for her oldest brother Ethan's research project, the "Luna Sleep Project." She decided to pay back the family for raising her with a thirty-year deep sleep and donated her corneas so her blind second brother, Lucas, could see again. Only after she was gone did the Johnsons discover that Luna was their real biological daughter all along, leaving them drowning in regret. Thirty years later, the experiment succeeded, but the awakened Luna had forgotten everything.
