The success of Lovely Runner has seen Kim Hye-yoon become one of 2024’s biggest K-drama stars, but her character in the time-travel series is far from her only praiseworthy role. Kim Hye-yoon’s career began in 2013 as she took on a minor part as the teenage version of actress Ko Do-young in the TV novel, Samsaengi. For years, she continued to take on small roles in some of the best K-dramas of all time, including Goblin and The Legend of the Blue Sea, before beating 200 other actresses to play Kang Ye-seo in SKY Castle.
