Adopted by the Luther family, the orphan Luna Luther once had three doting brothers and a loving home. But when the Luther family's biological daughter Sasha Luther returned, Luna's life turned into a nightmare—bullied and treated as nothing more than a "replacement".
Repeated misunderstandings and wounds left her utterly broken. In the end, Luna volunteered for her eldest brother's scientific project, The Moonlight Sleep Project, choosing thirty years of deep sleep to repay the family's kindness. She even donated her corneas, allowing her blind second brother to see again.
Only after her disappearance did the Luther family learn the heartbreaking truth—too late for regret.
Thirty years later, the experiment succeeds. Luna awakens, but all her memories are gone.
