Running Man's Lee Kwang-soo might be in love with Jeon So-min and there is a reason why it might be true. The actor has had a sleepover at the South Korean actress's house.

As noted by website Soompi, on the June 4 episode of 'Running Man,' the members were headed to Japan. It was on their way to the first mission that the members revealed about Lee Kwang-soo's sleepover at Jeon So-min's house.

Yang Se-chan, who joined 'Running Man' with Jeon So-min was naturally curious if anything happened at her house. Lee Kwang-soo said it was a misunderstanding, to which Yoo Jae-suk teased him even more and said, "Nobody is misunderstanding anything. We have no interest in your relationship."

Lee Kwang-soo went on to explain that he and the producing director (PD) of SBS's 'Running Man' had dinner together that day. Following this he had taken a cab home. However, he was in such an inebriated state that the cab driver found Kwang-soo's phone and called the last person in his phone log, who so happened to be Jeon So-min. He was then left to her care.

What happened next was even more interesting. Kwang-soo said, "I was sleeping but I felt someone looking at me."

And that person was none other than Jeon So-min's father. He added, "Jeon So Min's father was looking at me through the gap in the door. I was so surprised and apologized but it turned out he wanted to take a picture with me."

Jeon So-min added more fuel to the fire by adding, "The taxi driver definitely said he was dead drunk, but as soon as he heard my voice he woke up immediately." This last bit is particularly interesting. It may be that the two have feelings for one another, but they may just be very good friends, nothing more.

Soompi also mentioned that Song Ji-hyo, Kim Jong-kook and Haha were able to tour Yokohama in that episode. However, Yoo Jae-suk, Ji Suk-jin, Lee Kwang-soo and Yang Se-chan were competing to find out who would get punished.

The next episode of "Running Man' airs on June 11 on SBS network.
