HaHa hinted at Kim Jong Kook and Yoon Eun Hye's past relationship.

On a recent video posted to HaHa's 'HaHa PD' YouTube channel, the variety show star went over his past history on popular shows like 'Nonstop', 'X-Man', 'Running Man', and 'Infinite Challenge'. 'X-Man' is known for featuring onscreen celebrity couples or pairings, and Kim Jong Kook and Yoon Eun Hye were one pairing that made an impression. However, their onscreen romance soon led to rumors about a relationship offscreen, which was never confirmed.

Producers asked HaHa, "What viewers were most curious about was Kim Jong Kook and Yoon Eun Hye. Do you have any behind-the-scenes stories?" HaHa then responded, "I can't tell you that. I'd die (from Kim Jong Kook)! To be honest, I think it's one of the greatest scenes in the history of love lines on variety shows," referring to when Kim Jong Kook put his hands over Yoon Eun Hye's ears.
