A year and a half ago, Lucia, through her adoptive mother's scheming, accidentally ended up entangled with Mafia boss Dante and became pregnant with twins — and during childbirth she suffered massive hemorrhage, while her healthy daughter was bought by the scheming woman Vanessa to pass off as a mob heiress! A year and a half later, to raise the surgery fee for her son Nico, who suffers from heart disease, the nursing Lucia stumbles by chance into becoming the Dante household's demanding "exclusive wet nurse" — and on the way to her interview, her breast milk unexpectedly saves the severely wounded, dehydrated Dante. After entering the estate, the vicious female rival Vanessa harasses her relentlessly, but luckily the eighteen-month-old "genius hacker cutie" Nico escorts her all the way — not only hacking into the estate's security to savagely torment the green-tea woman, but even teaching his old man online how to protect his wife. As Nico's condition worsens and he needs a blood transfusion, Dante is shocked to find his rare blood type perfectly matches Nico's — and the long-buried truth is completely torn open. In a fury, Dante blacklists the vicious female rival before the entire family, and in the name of the Mafia godfather, dotes on Lucia and the two cuties to the heavens!
