For the March music release of his monthly series, Yoon Jong Shin personally took over vocals instead of featuring another artist.

He dropped ballad "Old School," which really provides a nostalgic feeling about love as he hopes his loved one finds somebody better. �The MV is sweet like the song as he sings his heart out with a soulful vibe that is a bit different from his normal singing style.
