A great fire not only claimed the lives of Mia's parents but also burned away her entire life. Upon learning that the fire was no accident but arson deliberately set by the wealthy heiress Blair, the flames of vengeance ignited in Mia's heart. To exact her revenge, Mia dropped out of university, took medication to induce lactation, and moved into Blair's fiancé's mansion as a wet nurse, using her plump and alluring body to slowly break down the man's defenses. What she wants is not just Blair's regret, but also her fiancé, her status, and the entire life she built on lies.
