ZE:A's Kwanghee is melting hearts with this snapshot he took with�MBLAQ's Lee Joon! On July 16th, Kwanghee tweeted, "Today, I did a radio program with Lee Joon. He is such a loyal friend! Because our promotions are during the same time, we are both a big help to each other. Our "Watch Out" is good, and Joon's "Mona Lisa" is also good too! I think we will meet again as nominees for first place. Right, Joon?!" In the attached picture, both Lee Joon and Kwanghee are seen posing happily for the camera. Both singers look especially very friendly with each other, but what caught fans' attention the most was Kwanghee's dazzling white smile. Netizens commented, "Both of you, good luck!" "They look very close with each other." "Kwanghee's teeth are so noticeable." Source + Picture: OSEN via Nate
