In this health and wellness reality program, the cast members and guests take on a fasting challenge for 24-hours in order to cleanse their digestive systems of society's unhealthy, processed ingredients. Chani, who confessed that he endured an irregular meal pattern while filming for his drama 'SKY Castle', chose to take on the fasting challenge in order to return to normalcy.
Hearing that Chani would be taking on the 24-hour fasting challenge, fellow SF9 member Dawon volunteered to suffer as Chani's partner. The two then tried to come up with punishments in the case that either violated the rules of fasting by eating or drinking! At first, Dawon jokingly suggested, "Shaving one eyebrow..?" But after a few options, Dawon named bungee jumping as an option, and Chani complained, "No, I might have a heart attack in the middle of it... I really can't bungee jump." Dawon remarked, "I can't even ride the pirate ship ride," and Chani added on, "Even watching [people bungee jump] on TV makes me scared."
In the end, Chani agreed to make bungee jumping the punishment, confidently claiming that all he had to do was succeed with the fasting challenge.
Later, Chani led his fellow members to a sundae (blood sausage) restaurant for his final meal before starting his 24-hour countdown. During their meal, Youngbin asked, "Our fans know you as a fried chicken lover. Chicken vs. Sundae stew?" Chani answered without hesitation, "Sundae stew. It used to be chicken but... this [sundae stew] won me over."
