SHAUN has officially made his first comeback since completing his military service!

On May 9 KST, the singer-songwriter unveiled his new single album '#0055b7,' featuring double title tracks "BLUE" and "Closed Ending." 

The two tracks tracks have a similar theme yet a completely different sound. "BLUE," featuring 'Show Me The Money 9' rapper Wonstein, fuses electric guitar with a hip-hop sound with lyrics that express the emptiness and lingering feelings that anyone who has ever felt in love would have experienced. "Closed Ending" has a sensuous melody similar to SHAUN's hit song "Way Back Home" and deals with the emotions of someone preparing for a break-up.
