It was revealed that singer Kwon Eun Bi and actress Joo Hyun Young were high school classmates. They appeared on SBS's 'Running Man' on the 17th, along with other guests.

During the show, Kwon Eun Bi spoke about Joo Hyun Young, mentioning their high school connection. She playfully teased Joo about her dancing skills, which, according to Eun Bi, haven't changed since high school. In response, Joo disclosed that Eun Bi used to dance sexy dances in the hallways, to which Eun Bi admitted thinking she was very popular back then.

The episode's race was based on the concept of 'less is more,' a reversal of the usual format where contestants aim to collect fewer coins to win. Kwon Eun Bi, teaming up with Yoo Jae Suk, Kim Jong Kook, and Yang Se Chan, showcased her acting skills in a game where they had to explain given words through acting. She successfully communicated the right answers with her expressive acting.

There was also a 'Colorful Dice' game. Eun Bi, exclaiming "life is a gamble," bet 560 out of her 587 coins, causing her coin count to dramatically increase and bringing laughter to the set. She continued her bold approach in the 'Lucky Draw' segment, betting all her coins again, but unfortunately picked the wrong option, leading to more laughter.

The final mission involved reducing the coin count of the team with the most coins. Kwon Eun Bi, with her daring bets, significantly increased the coin count for her team, causing teammate Kim Jong Kook to demand a promise from her not to appear again. Jong Kook's anger caused everyone to burst out laughing.

Eun Bi ended the show by expressing her enjoyment in participating with her esteemed seniors. MC Yoo Jae Suk praised her audacious betting, humorously calling her a real "moth to the flame."
