Sung Si Kyung is the voice behind "Leaning on You" for 'The Tale of a Gumiho' OST.

In the music video, Lee Yeon (played by Lee Dong Wook) and Nam Ji Ah/Ah Eum (Jo Bo Ah) settle in home together like a married couple would do. "Leaning on You" is a lyrical and romantic ballad about the fateful love between the two main characters.
