The CEO's Long-Lost Savior

The kidnapped teenage boy was rescued at great risk by Zara Lin, with a wristwatch becoming the token of gratitude. Ten years later, the boy has grown into a top CEO, returning to find his savior. The greedy Auntie Guinevere, wanting to cling to the wealthy family, has her biological daughter pretend to be the savior. The CEO notices constant inconsistencies, conducts secret investigations to uncover the truth, exposes the imposter's lies, finally finds the real savior, resolves the decade-long misunderstanding, and the two have a mutual love that leads to a happy ending.
