Golden Era(2000)

Golden Era follows two boys from opposite sides of the economic divide—poor Park Kwang Chul and wealthy Lee Jae Hoon—who forge an unlikely friendship. Years later, they reunite as young men working together in banking. When they help Hee Kyung, who grew up as Park Kwang Chul's sister, search for her biological father, the trio unearths painful secrets that reshape their understanding of their shared past. The series explores how childhood bonds endure through class differences and how the pursuit of truth can upend carefully constructed lives.
