In the heart of the city, a glass skyscraper pierces the sky. Engraved at the top is the name 'Changcheon Group.' To some, it was an object of envy; to others, an unreachable world. And at the center of that world stood one person: Han Jaeha, the only son of Changcheon Group. A life destined for succession from the moment of birth.
