Biography
Kim Sung-kyu, known mononymously as Sunggyu, emerged as the foundational pillar of the boy band Infinite. Debuting in 2010, his role extended beyond main vocalist; he was the group's emotional anchor and strategic leader, guiding them through a competitive era. His clear, powerful tenor became a signature of Infinite's sound, often carrying their most dramatic hooks. While the group achieved massive success, Sunggyu also carved a distinct solo path, releasing albums that showcased a more introspective, rock-influenced side. His artistic journey reflects a deliberate shift from idol performer to respected singer-songwriter, earning him a durable reputation for musical sincerity in an industry often marked by flux.
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.
Kim was born in 1989, 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.
