Kim Hye-yoon
Kim Hye-yoon (김혜윤) is a South Korean actress born November 10, 1996, in Seongnam, who turned a supporting role into a cultural moment and never looked back. She broke through in JTBC's Sky Castle (2018), playing overachiever Kang Ye-seo in one of the most-watched Korean dramas of the decade, a performance that earned her the nickname "nation's little sister" from Korean media. The role launched her from character actress to leading lady overnight.
Signed with Artist Company since April 2024, Hye-yoon turned the lead in tvN's Lovely Runner (2024) opposite Byeon Woo-seok, a time-travel romance that became one of the year's biggest drama hits in Korea and across Asia. Her portrayal of Im Sol anchored the show's emotional core and drove the pair's Salon Drip promotional appearance to 18.56 million YouTube views. She graduated from Konkuk University with a B.A. in Film Studies, consistently on merit-based scholarship while actively filming.
