This is the love story of the youngest name-partner of a corporate law firm in Seoul, Jennie Kim, and her newly hired bodyguard, Jongin Kim. Because of her job, Jennie hasn't dated anyone and hasn't had a proper love-life since college, so when she meets her new bodyguard she questions herself and her feelings. Jongin, on the other hand, doesn't like playing around too much and is straightforward. What happens when he confesses his feelings to Jennie? Will she accept them?
