Death Certificate Signed, Family Begs Forgiveness

Helena, the adopted daughter (actually the real heiress) of the Vance family, suffers endless coldness, favoritism, and false accusations from her family after the return of the imposter, Kingsdale. Utterly desperate, she secretly donates bone marrow to Carter and signs up for a perilous interstellar mission led by Grant, her family signing her death certificate without her knowledge. Only after Helena boards the spaceship and leaves Earth do her family stumble upon the truth, filled with remorse and waiting for thirty years. Thirty years later, Helena, still looking eighteen, returns to Earth. Facing her white-haired, weeping family, she resolutely leaves as if they were strangers, pursuing her freedom.
