Arthur, Cassia's arrogant childhood friend, gave the necklace meant for her—the “fake heiress”—to Emma, the newly returned “real heiress”, to test Cassia's love. Seeing comments foreshadowing a tragic fate, Cassia woke up, cut ties with the man she'd loved for nineteen years, and left to study in Europe. Regretful Arthur begged for reconciliation, but she refused coldly. When Emma accused her of plagiarism, Cassia fought back fiercely. Arthur then curbed his possessiveness and quietly supported her career. Ultimately, Cassia escaped her tragic fate, became head of a global beauty giant, and found a love equal to her own strength.
