Sunggyu is gearing up to release new solo music!

On March 21 KST, the INFINITE leader unveiled concept photos to promote his upcoming song "HUSH," the title track on his new single album 'Won't Forget You.' In the images, he poses with longer, blond hair, looking deep in thought in two different black-and-white photos. As the concept photos are titled the 'A version,' there is likely to be even more concept photo sets being released leading up to his solo comeback.

Meanwhile, 'Won't Forget You' is Sunggyu's final solo release with INFINITE's agency Woollim Entertainment as his contract expired earlier this year. The album is set for release on March 29.

Check out the concept images below, and stay tuned for more teasers ahead of this exciting comeback!
