In her previous life, she accidentally found an extraordinary fish pearl, only to have it forcibly taken by her greedy in-laws. She was thrown out of the family home, and her own daughter was sold to an old bachelor, leaving her with a tragic fate. Reborn, she returns to the very day the tragedy began. In front of everyone, she swallows the shimmering silver pearl and unexpectedly unlocks supernatural abilities underwater, gaining access to endless treasures beneath the sea. When her vicious mother-in-law and her family violently demand the pearl and try to drown her, she finally awakens after having died once. No longer willing to endure their cruelty or remain weak, she publicly exposes her in-laws' greed and wicked deeds, protects her young daughter, and begins an extraordinary journey of revenge and triumph.
