BTOB's Minhyuk released sexy photos for his solo debut. 

Prior to making his military enlistment this year, Minhyuk is treating fans with the 1st solo album 'Hutazone.' In the first set of concept images, the idol star stepped aside from his gentle, sweet charms and went for a darker, sexier, stronger look with light blonde hair. He also exposed his sexy abs.
