After twenty years of biding her time, Victoria—seeking revenge—infiltrates the wealthy Sterling family as a maid under the alias Flora. Cloaked in a humble guise, she executes a calculated plan: exposing a sham marriage on livestream, driving a wedge between mother and son, and gathering evidence of the massacre that destroyed her family. Though she initially views Gabriel, the son of her enemy, merely as a tool, a genuine bond blossoms between them amidst their shared darkness. On the night the truth comes to light, Gabriel dies shielding her from a knife attack in a burning warehouse. Having finally exacted her revenge, she spends the rest of her days in solitude, cherishing memories of the "Prince of the Piano" to the strains of the *Moonlight Sonata*.
