A seemingly chance encounter brings together two people with starkly different personalities. She is rational and independent, yet deeply skeptical of love; he is bright and confident, yet carries a secret he keeps hidden from the world.

As they face a series of challenges—involving money, social status, and the harsh realities of life—they come to realize that what is truly priceless is not material wealth, but the trust and protection they offer one another. When love collides head-on with reality, what will become of this bond with a man who proves to be truly "priceless"?
