About Lovely Runner
Lovely Runner (Korean title Seonjaeya Dallyeo, often rendered in English as Run On, Sun-jae) is a 2024 South Korean time-slip romance that aired on tvN. Adapted from the web novel Tomorrow's Best by Kim Bbang-i, the series follows Im Sol, a devoted fan whose life has been quietly held together by her admiration for Ryu Sun-jae, the lead vocalist of the band Eclipse and her long-time idol and first love. When tragedy strikes and Sun-jae dies, a grieving Sol is mysteriously sent fifteen years into the past, where she meets him again as a teenager.
Determined to rewrite the future, Sol resolves to save Sun-jae's life and protect the bright, kind-hearted boy he was before fame and heartbreak changed him. As she repeatedly travels between timelines, she discovers that her own choices are deeply entangled with his, and that the boy she is trying to rescue has loved her far longer than she ever realized. What begins as a rescue mission slowly becomes a tender, swoony second-chance love story.
Praised for its warm tone, emotional sincerity, and the chemistry between its two leads, Lovely Runner became one of the breakout K-dramas of 2024, propelling its cast to stardom and earning a large international fandom. Its blend of nostalgic 2000s atmosphere, gentle fantasy, and heartfelt romance made it a fan favorite that drove strong streaming numbers and widespread social-media buzz.
