After the victorious project with SISTAR's Soyu in their duet song 'Some', JungGiGo is a week ahead preparing for his next project.

Comeback photos of him are uploaded through STARSHIP Ent. twitter account showing the artist in a semi formal suit with a sexy feel.

JungGiGo is going to release a new single on April 17, and the next artist he's going to collaborate with will be revealed soon. Any guess?
