Biography
Ong Seong-wu's path to stardom was a public audition on the high-pressure stage of 'Produce 101.' His calm demeanor and sharp performance skills secured him a spot in the supergroup Wanna One, where he experienced a whirlwind of record-breaking success. Rather than resting on idol fame, he made a calculated and successful leap into acting. His debut in 'At Eighteen' was a revelation; he played an isolated teenager with a sensitivity that silenced any doubts about his credibility. Ong chooses roles that are often quiet and complex, like a young man with Asperger syndrome in 'More Than Friends,' demonstrating a commitment to challenging work over easy popularity. This deliberate career shift has established him as a distinct figure in the industry—an idol who successfully rebuilt himself as a serious dramatic actor, earning respect on his own terms.
Millennials
1981–1996
The first digital natives. Grew up with the internet, came of age during 9/11 and the 2008 crash. Highly educated, deeply indebted, slower to marry and buy houses. Redefined work, identity, and what it means to be an adult.
Ong was born in 1995, placing them squarely in the Millennials. The events that shaped this generation — the internet revolution, 9/11, and the 2008 financial crisis — shaped the world they entered and the choices available to them.
