Ko Sung-hee

Ko Sung-hee is one of those actresses who quietly earns your respect without making a lot of noise about it. Born in Columbia, Missouri — which is a fun biographical wrinkle for a South Korean star — she grew up to study at Sungkyunkwan University and eventually landed her first leading role in the 2014 fantasy-period drama Diary of a Night Watchman, which is no small thing: period dramas in Korea are high-pressure gigs that demand physical commitment and emotional range. She's the type of performer who slots into both film and television naturally, and still in her early thirties by 2024, she hasn't even hit her peak yet. I genuinely think the best chapters of her career are still ahead of her.
