ZE:A Kwanghee released a photo taken with UFC fighter Choo Sung-hoon.

On April 4, Kwanghee tweeted a photo with Choo with a comment, "Good night, my bro."

In the photo, Kwanghee smiles happily next to Choo Sung Hoon, also with a big smile. The two of them first crossed paths at SBS' variety show "Rules of the Jungle" and have apparently continued to build their friendship as close brothers.

Currently, Kwanghee hosts SBS "Inkigayo" and continues to show off his unique, pleasant character in many different avenues. Choo Sung Hoon is currently a mixed martial artist in UFC middleweights.
