Lia, a 23-year-old ordinary girl, joins a secret surrogacy program to earn money, tasked with bearing an heir for President Elliot of the United States. The rules are brutal: whoever gives birth to the heir first will become the First Lady, while the losers will be erased completely. Lia only wants to get paid and leave, but she never expects that on the day of delivery, she gives birth to two puppies. To save her life, she lies about having a false pregnancy and is demoted to a White House cleaner. Even more shocking is that the puppies can transform into human children. President Elliot is actually a werewolf, the black wolf Lia rescued from severe injuries three years ago. Elliot has been searching for her through the surrogacy program all along. In the end, with Elliot's protection, Lia uncovers the villains' plot. She rises from a cleaner to the First Lady and builds a complete family with the werewolf president and their two children.
