Master of Destiny

Kwan Yeuk Nam is a legendary woman. After her husband committed suicide due to a business failure, she single-handedly raised her three sons to adulthood, also establishing her own business empire, Sun Hon Lik, in the process. Now ready to retire, she is prepared to pass down her empire to her three sons.
Eldest son Cho Chi Wang is quietly pursuing Nam's adoptive daughter, Hau Yee, but Yee is truly in love with Wang's younger brother, Cho Chi Yuen. When Yuen's girlfriend passes away, Yuen devotes his life and energy to his career, and Wang's position as heir to the empire is threatened. Sung Chi Wah, a new employee at Sun Hon Lik, seduces Wang and nearly tears his family apart. With her family and business at the brink of breaking down, Nam has no choice but to step up and formally pass down the business to Yuen.
Wah tells Wang that he is not the birth son of Nam. Disheartened at his family, the two team up to incarcerate Yuen. Just when Wang and Wah are about to overthrown Nam's reign, Yee returns just in time to save Yuen.
