In episode 18 of 'Go to the End! Solo Tour,' aired on E Channel and Channel S, Kim Joon-ho, Kim Dae-hee, Jang Dong-min, Yoo Se-yoon, and Hong In-gyu tour major attractions in Gimcheon alongside Gimcheon native Park Young-jin.

On this day, the members visited Jikjisa Temple, located in Samyeongdaesa Park. Park Young-jin introduced a nighttime attraction in Gimcheon that families can enjoy, saying, "If you go there, there's plenty for kids to play with even at night." Kim Joon-ho, however, could not hide his puzzlement, saying, "Coming here at night with kids? There's nothing to do here — what for?"

Park Young-jin explained that the Municipal Museum transforms starting at 7:30 p.m. under the name 'Osam Hideout.' 'Osam Hideout' is a space where visitors can enjoy adventures with 'Osam,' the crescent bear mascot of Gimcheon, and a laser device reminiscent of the film 'Mission: Impossible' installed at the entrance drew the members' interest. Hong In-gyu dodged the lasers, exclaiming, "Wow! It's a black hole! It feels like I'm being sucked in!" while Kim Joon-ho expressed his delight, saying, "Wow! It's Osam!" On site, Kim Joon-ho also greeted family visitors, showing off his 'dad smile.'

After finishing the nighttime tour, the members moved to a private house stay in Gimcheon that Park Young-jin had booked. Park Young-jin said, "I heard private house stays are popular these days, so I picked one with a similar vibe." Hong In-gyu responded, "Young-jin, I'm suspicious because you're such a cheapskate."

The members then played a solo tour game with the lodging costs at stake. Jang Dong-min proposed a 'Liar Game' and asked Kim Joon-ho to "give an easy keyword to start," to which Kim Joon-ho replied, "I'll handle it myself! I'm also a third-round solo player."
