Davichi's Lee Hae Ri is the voice behind "Maybe" for the 'Her Private Life' OST.

"Maybe" is about slowly developing real feelings for each other despite a false start, and the music video above features romantic scenes between Sung Duk Mi (played by Park Min Young) and Ryan Gold (Kim Jae Wook) as they go from collaborators to an actual couple.
