Fans and 'Running Man' members might wonder whether Lee Kwang-soo will ever stop getting into trouble. Fans already know the many punishments Kwang-soo gets for himself by failing missions and the hilarious incidents that happen as a result. This time, things may have become slightly more serious for the tallest 'Running Man' member.

As noted by website Soompi, during filming for the upcoming episode of 'Running Man,' a surprising story of Lee Kwang-soo and Apink's Bomi was revealed. Actor Shin Sung-rok and Bomi appeared as special guests for an upcoming episode of the SBS variety show. Curiously, Bomi was seen appearing awkward around Lee Kwang-soo during the filming of the episode.

The cast members took notice of that and naturally asked her if something was wrong. Her answer was a bit shocking for the 'Running Man' members. Bomi revealed, "After filming last time, Lee Kwang-soo video called me after drinking and it was actually a little uncomfortable." Interestingly, Bomi and Kwang-soo had a love line in an April episode of 'Running Man.'

Lee said, "I treated her the same as I treat Apink's Eunji, who I am close to. It's not like that [indecent intentions]!" Even though Kwang-soo said he had no ill intentions towards her, the other 'Running Man' members remained suspicious of him and kept teasing him throughout filming.

Previously, Lee Kwang-soo had a sleepover at Jun So-min's home because he was drunk and out of his senses. The taxi driver found his phone and called the last person on his phone log, which was Jun So-min.

Lee Kwang-soo reportedly seems to fall in love with his female guests, especially if he is paired opposite them. He allegedly fell for singer Soyou on one episode and was eager for a back massage she was giving to the other 'Running Man' members. When his turn came, she pressed her feet so hard on his spine that he screamed from the pain.

However, this drunk call incident is perhaps the only time that things may have become slightly serious for Bomi and Kwang-soo. Seeing as 'Running Man' members and guests were laughing and having fun while participating in the activities of the episode, things seem to look alright.

The next episode of 'Running Man' airs on October 15 at 4.50 p.m. KST. There will be a race where it will be decided who will accompany Kwang-soo on a trip to Australia. There, he will have to receive a punishment by attending a crocodile diving experience called 'Cage of Death.'
