Taeyeon solo, video clip is closing scene from KDrama Hong Gil Dong ep7 starring Sung Yu Ri & Kang Ji Hwan. I subbed this with my friend jihaeshi.
D/l this song from: http://www.sendspace.com/file/7st8z3
Yuri's character (Huh In Nok) goes to try to prevent KJH (Hong Gil Dong) from turning himself in to the royal guards in order to save the lives of many innocent people. So far the defining moment in this touching drama, highly recommend seeing this show.
