One Way members Peter and Young Sky have formed their own sub-unit group titled D2O (Detour).

The duo have just released their brand new single titled "Butterflies", which features 5 tracks in total including three songs, and two instrumentals!

Though most of us are familiar with the experience of getting butterflies in our stomach when falling in love, the track "Butterflies" talks about how the return of a departed love can give you the wrong kind of butterflies.

The other two songs included are "Secret," which is a sexy and smooth R&B song, and the English version of "Butterflies".

Be sure to support both Peter and Young Sky, and all the hard work they put into the album, by purchasing the single on iTunes here.
