Billionaire Heir in Disguise

Frederick, son of the world's richest man, works incognito on a construction site for five years to find true love. After saving 300,000 for his wedding, his fiancée Sabrina betrays him for a richer suitor, Warren, and publicly humiliates him. When Frederick shows his Gold Black Card, Warren dismisses it as fake. The card is verified, but the Wang family still accuses him of theft. Frederick's father then reveals his true identity: he is the heir to both the family fortune and the Dragon Group. The betrayers face consequences as Frederick takes over the business, launching a new project that values integrity above all.
