25-year-old Lila, facing premature ovarian failure and desperate to have a child, catches her boyfriend Ethan cheating. She meets 32-year-old billionaire Adrian at the hospital, mistakenly thinking he’s a sperm donor and she a surrogate candidate. Learning Lila needs money for her father’s medical treatment, Adrian offers a surrogacy deal, later adjusted to joint custody and a fake engagement. As they fall for each other, they face obstacles from Ethan (Adrian’s nephew), Adrian’s ex Vivian, and his family. Adrian gives up his fortune for Lila; they clear misunderstandings, marry legally, and welcome their baby happily.
