The end of Running Man is approaching, but the members are making it hard to say goodbye with their recent episode, which showed off their hilarious personalities and friendship.

In the episode, each cast member was made to sit for lie detector test based on questions by fellow members. The segment shone light on some of the things we never knew, including what Kwangsoo thinks of best friend Song Joongki’s popularity and Kim Jongkook’s feelings for Yoon Eunhye, who has been in a “love line” with him since their X Man days.

When asked if Kwangsoo thought he was as popular as Joongki, he confidently answered positively, much to the surprise of his fellow members. But here’s the catch: according to the lie detector machine – which sends a jolt of electricity to their hands if it detects a lie – Kwangsoo was telling the truth when he made that claim.

His actions left the members flabbergasted, and Haha even jokingly said he was a “psychopath”, but Kwangsoo defended himself and said, “I’m entitled to my own opinion.”

As the game progressed, Song Jihyo asked Jongkook whether he still liked Yoon Eunhye, whom he has shown an interest in since they appeared together on X Man 10 years ago. While he denied it, the lie detector sent a jolt of electricity to his fingers, indicating that he was lying. As the other members teased him, Kwangsoo said, “To be honest, he’s so clingy that it’s scary!” He added, “He’s a fool who only loves one person.”
