The idol, who appears to be the last person in the room, decided to whip out his cellphone to take a cheeky picture backstage. Fans were drawn to his pearly whites and blemish-free skin; some male fans even asked Kikwang for some beauty advice.

Comments included:�"Because of oppa's healing smile, I'm feel revitalized!", "Asking as a guy, what is your skin secret?", and "Can't wait for your concert!!!"

B2ST will soon be holding their 'Beautiful Show'�concerts�on February 4th and 5th at the Seoul Olympic Gymnastics Stadium. Afterwards, they will then embark on their 21-city world tour.
