Singer Sung Si-kyung will release a digital single on Oct. 19, his first music release since his eighth full-length album, "Siot," in 2021.

Sung's agency SKJaewon said the song will be "a deeply emotional ballad" for the fall season. The single's title has yet to be announced.

Though Sung has participated in soundtracks for TV shows, he has not released new music for over two years.

Sung debuted in 2000 and is known for "The Road to Me" (2001), "On the Street" (2006) and "You're My Spring" (2010).

He is also active as a television personality, appearing on shows such as "Witch Hunt" (2013–15), "Non-Summit" (2014–17) and most recently on the "Risque Business" on Netflix.

He also runs a YouTube channel with more than 1.6 million subscribers. It features videos of him cooking, eating out at restaurants, and having conversations with other celebrities.
