Serena, a post‑apocalyptic warrior, transmigrates into a book and becomes the birth mother of Noah, the great future villain. In the original novel, Noah would imprison his own mother until her death when he grows up. After transmigrating, she resolves to change their fates, raise her son, make money, and live a fulfilling life. Leveraging her combat and tactical skills, she thrives in underground fighting arenas and the esports scene — yet her five‑year‑old son Noah keeps a tight rein on her pocket money, daily routine, and fried‑chicken allowance. Adrian, Noah’s biological father and a top‑tier tycoon, shows up and signs a night‑assistant contract to pursue her. While Serena chases wealth and takes down villains, Noah supervises his mother and assesses his father. Amid their chaotic and hilarious daily lives, the three gradually heal one another, and Noah escapes his villainous fate.
