Known as the jokester, ZE:A's Kwanghee is a perfect target as the substitute father figure to entertain the daughter of MMA fighter Choo Sung Hoon named Sa Rang. It was also reveled that Kwanghee was in Japan that made it more easier for Choo Sung Hoon to get his service as substitute father. lol

According to one of the representative of 'Superman Is Back', he revealed to Star News, "Kwanghee's guest appearance is not because of the staff but Choo Sung Hoon's ties with him... Kwanghee visited Japan for their concert schedule, and Choo Sung Hoon invited him."

He continued saying "We were able to see a new side of the Kwanghee we see on shows. Although Sa Rang looked like she was pushing away Kwanghee in the preview, please anticipate whether or not they can become close during the live broadcast."

Watch Kwanghee's fatherly side on 'Superman Is Back' this coming December 15th Korean Time and you could be the judge id his effective as a father figure!
