T-ara's Soyeon is the voice behind "One Love" for the 'Homemade Love Story' OST.

In the music video above, a mother comes across her daughter Lee Hae Deun (played by Cosmic Girls' Bona) as she goes through a rough time as a trainee and does what she can. "One Love" is a cover of Park Sang Min's track of the same name in 1998, and it's about loving someone from afar.
