Although it's not his own official release, it's still good to hear from the rookie singer again as he hasn't been actively promoting since the beginning of this year.

"Cool Guy" is the theme song for Goo Dae Young (played by�B2ST's Doojoon) and gets you grooving along to its funky beat. The song was composed by composer illi and written by webtoon writer Mitty (Hong Seung Pyo). Much like the title, Eric Nam helps give off the confident attitude of Goo Dae Young as he sings along to the witty lyrics.

For those who missed Eric Nam's voice, listen to "Cool Guy" above!
