"One & Only" is the first and title track from single album "Go Won" by member Go Won of LOOΠΔ. It was released on January 30, 2018 as the eleventh part of the "Girl of the Month" project along with a Music Video on YouTube.


Go Won’s titled track ‘One&Only’ is about self-love.

Even when it feels like the existence of oneself seems irrelevant in the world and may feel very little among others, Go Won sings, “it’s not a coincidence that I’ve met myself” and emphasizes how she met herself, ‘one and only’, is precious.

The version of the ‘One&Only’ distributed online has been mixed in 3-D to stimulate stereognostic perception of the listeners when listened on either earphones or headphones. The CD version of the track will be the ‘original mix’ version as a perk for fans who purchase the CD.
