Ha Sung Woon is the voice behind "Think of You" for the 'Her Private Life' OST.

"Think of You" is the 6th track to be released for the OST, and it's a beautiful orchestral song about holding back for your feelings for the right moment to express your love. The music video above features Ha Sung Woon in the studio as well as scenes from the drama as Ryan Gold (played by Kim Jae Wook) and Sung Duk Mi (Park Min Young) get closer and closer.
