Twins Jae-min and Jae-hyuk were separated by a divorce that split more than a family: one raised as the chaebol’s flawless heir, the other in a fishing town by a mother who never explained the checks she burned every month. At twenty-eight, a hospital mix-up throws them into the same room — and neither brother likes the mirror. As the heir suffocates under a father’s empire and the fisherman discovers a talent for the boardroom no one taught him, both start asking the question the family spent a fortune avoiding: which life belonged to whom? A moving family saga about nature, nurture, and the price of the swap nobody admits happened.
