Ella, a top industrial designer, selflessly provided her core technology to her husband Davis’s tech company after their marriage, working tirelessly without complaint—only to be brutally murdered by her husband and his mistress, Candy, who was disguised as a companion robot. Reborn three days before her murder, Ella resolved to turn the tables and seek revenge. She secretly gathered evidence and, at their anniversary party, publicly exposed the true nature of the two conspirators, leaked the company’s core blueprints, and decisively filed for divorce before walking away. Faced with Davis’s desperate pleas for reconciliation and Candy’s malicious rumors, Ella stood her ground and filed a lawsuit to recover her unpaid wages. Later, Ella fell in love with architect Noah, and together they developed the genuine companion robot, Eva, completely crushing Davis’s company. Candy fled with the money, while Davis was left with nothing and filled with regret. Ella traveled abroad to start a new life; three years later, Davis quietly stepped in to resolve a crisis for her, after which he vanished completely from her life.
