Chloe Shaw, a graduate of Parsons School of Design, rescued Ethan Cross, the CEO of Cross Group, who was injured on a rainy night. After a one-night stand, Chloe left quietly, accidentally leaving behind her exclusive design badge. Her best friend Luna Reed picked up the badge, impersonated Chloe, moved into Ethan’s penthouse apartment and became his fiancee-to-be. Later, Chloe joined Cross Group relying on her professional strength and became Ethan’s subordinate. As they spent more and more time together, Ethan gradually saw through the truth.
