Mistaken for the Mistress, I'm the Billionaire's Wife - Episode 1

Introduction: Laura Gates has been secretly married to billionaire CEO Simon Gates for three years. The day she finds out she's pregnant, she brings him a homemade lunch to share the news, but his unhinged secretary Lily mistakes her for a gold-digging mistress. Lily is convinced she's the real Mrs. Gates. She pours scalding soup over Laura's head, crushes the childhood ring Simon gave her, and turns the entire office against her until Laura loses the baby. Simon is just one door away, and he has no idea. When he finally recognizes his broken wife, the cold, composed CEO goes mad.
