Soccer player Park Ji Sung kept the promise he made to IU.

IU held her first solo concert 'Real Fantasy' on June 3rd at Kyung Hee University's Peace Hall and Park Ji Sung was present. The reason Park Ji Sung came was because he made a promise with IU on SBS' 'Running Man'.

At the start of the second half of her concert, IU said, "There is a very special guest present today in the audience. We met through SBS 'Running Man' and I asked him to come to my concert and I am very grateful that he came."

Park Ji Sung was then surprised when he was suddenly shown on the electronic display board. He was initially shocked, but then smiled and waved.

Netizens who heard Park Ji Sung went to IU's concert commented saying, "Did you give up on the Mysterious Park Ji Sung? He has great manners", "I guess Park Ji Sung is an uncle fan too", "I would be so nervous if Park Ji Sung was present at my concert", and "A successful fan".

On another note, other celebrity guests present at her concert were 2AM, Ra.D, Heo Gyung Hwan, and Lee Seung Ki.
