Sung Si-kyung Joins OST for JTBC’s New Drama ‘Surely Tomorrow’



Singer Sung Si-kyung participates in the OST of JTBC's new Saturday drama 『Waiting for Gyeongdo』 to deepen the emotional line of the work.

Sung Si-kyung's OST 'Some Day, Some Hearts' will be pre-released at 6 p.m. on December 4th.

This song was composed and sung by Sung Si-kyung herself, completing the lyrical atmosphere with her unique emotional vocals.




'One Day, One Day, One Heart' was created around the emotional flow of Lee Kyung-do's character played by Park Seo-joon in the drama. The lyricist Shim Hyun-bo completed the lyrics based on the script and delicately depicted the inner side of the character. Sung Si-kyung's light yet lingering tone is expected to increase the immersion of the song and perfectly blend with the atmosphere of the play.

Sung Si-kyung, who has been loved for her unique deep emotional ballad every winter, is expected to prove her presence like a 'song powerhouse' again this time.

Meanwhile, 'Waiting for Gyeong-do' is a real romance between Lee Kyung-do (Park Seo-joon) and Seo Ji-woo (Kwon Ji-an), who broke up after two relationships, reunite as an affair scandal reporter and the wife of the scandal party, respectively. It will premiere at 10:40 p.m. on December 6.
