Charismatic and extroverted Joo Yoo Rin is trying to make a living as a tourist guide, but because of her father's constant debts she has learned to lie on the spot and has lived on the run for most of her life. It is while running away from debt collectors that she meets Seol Gong Chan, a serious and responsible heir to a large hotel firm who is looking for a missing cousin his grandfather always regretted not being able to meet. But when the old man's health declines, Seol Gong Chan becomes desperate to give him at least some peace of mind, and hires Joo Yoo Rin to impersonate his missing cousin.
