On the October 10th episode of MBC's 'Radio Star', child actor Park Ji Bin from the drama 'May Queen' made his male co-stars envious when he revealed that his first kiss was with none other than f(x)'s Sulli.

The 'Top Child Stars' special featured Park Ji Bin, Oh Jae Moo, Lee Sae Young, and Noh Young Hak. After Park Ji Bin revealed the story about his kiss with Sulli, Oh Jae Moo, who is known to be a fan of Sulli, applauded him by stating, "I'm in awe."

Park Ji Bin continued to open up about his kiss scene as he explained, "I acted with Sulli once for 'Banjun Drama' and the scene called for me to trip over and accidentally lock lips with Sulli", leading Oh Jae Moo to stare at him, green with envy. Park Ji Bin further tested Oh Jae Moo as he commented, "Why are you looking at me like that? Are you jealous?" However, he then revealed that kissing Sulli had its down sides as he stated,"After filming the kiss scene with Sulli, I received a lot of hateful comments from f(x) fans."

Oh Jae Moo then hilariously responded, "I'm one of the f(x) fans who said hateful things toward Park Ji Bin", bringing laughter on set.
