From fiction to real life phenomenon: Lovely Runner’s Sudden Shower becomes a global hit

The band ECLIPSE in Lovely Runner consists of four members: Ryu Sun-jae (Byeon Woo-seok), Baek In-hyuk (Lee Seung-hyub from boyband N.Flying), Hyun Soo (Moon Xion), and Jay (Yang Hyuk). However, Sudden Shower stands as a solo song by vocalist Ryu Sun-jae.

In Lovely Runner, Sudden Shower (Sonagi) isn’t just a song but also a plot device. In the story, Ryu Sun-jae composes the track after encountering Im Sol, portrayed by Kim Hye-yoon, for the first time. During their initial meeting, she runs toward him holding a yellow umbrella as rain begins to fall suddenly, instantly capturing his heart.

That moment of quiet awe, wrapped in the innocence of first love, becomes the essence of the song. It reflects Sun-jae's feelings for Im Sol. Performed by Sun-jae in his idol persona, the song recurs throughout the series, weaving through multiple timelines in the time-slip narrative.

For Im Sol, Sonagi or Sudden Shower becomes a hauntingly beautiful melody that stirs something deep within her—even when she is unaware that the song is about her. For Sun-jae, it’s a musical anchor, connecting him to cherished moments of her that he refuses to forget—even when he doesn’t remember them or her.

Behind the scenes, Sudden Shower was written by songwriter Kim Soo-yoon, who captured the emotional weight of 2000s rock ballads and classic band sounds. The real-world track mirrors the fictional Sun-jae’s feelings, blending narrative and melody perfectly.

Originally created as part of the show's storyline, Sudden Shower quickly transcended the drama’s narrative to become a global fan favorite. The song's impact extended beyond the series, making waves on major music charts soon after its release.

On June 4, 2024, it entered the Billboard Global 200 at No. 199. The song outpaced Taylor Swift’s Anti-Hero and BTS member Jungkook’s Standing Next to You. It also debuted at No. 92 on the MelOn Top 100.

The momentum continued the following day as Sudden Shower was featured on M COUNTDOWN’s Monthly Pick segment. It became the first K-drama OST to receive this honor, further underscoring its crossover success and cultural impact. The song also earned the model-turned-actor Byeon Woo-seok the Favorite Global Trending Music award at the 2024 MAMA Awards.

In addition to Sudden Shower, ECLIPSE performed three more tracks for the drama's OST. These songs, sung by the actors portraying the band members, are Run Run, You & I and No Fate. All of these tracks are available for streaming on Spotify.
