In the 10th episode of the E Channel and Channel S variety show 'Going All the Way! Solo Burden Tour,' Lee Sang-jun's trip to Mokpo with the 'Dokbakz' members is featured.

In this broadcast, Kim Dae-hee, Kim Jun-ho, Jang Dong-min, Yoo Se-yoon, and Hong In-gyu headed to Gohado, a famous Mokpo landmark overlooking Yudalsan, along with Lee Sang-jun. Inside the moving vehicle, candid conversations about marriage and dating took place. When Lee Sang-jun revealed that he was the only one who had not married, Jang Dong-min pointed out that Lee Sang-jun "has high standards for the opposite sex but lacks the skills to meet them." Kim Jun-ho then stepped up, offering to pass on his dating know-how, but Lee Sang-jun showed a firm attitude, insisting that he did not need to hear any advice.

During this exchange, Hong In-gyu brought up the fact that Kim Jun-ho had married celebrity Kim Ji-min, showing a sense of pride. After a brief pause, Kim Jun-ho remarked, "Kim Dae-hee and I have decent looks," adding, "If anything, it's Jang Dong-min who needs advice," turning the scene into a sea of laughter. Not to be outdone, Lee Sang-jun retorted, "I won't be the one stuck with the bill in Mokpo."

The members' antics continued after boarding the Mokpo Maritime Cable Car. Lee Sang-jun persistently urged Kim Jun-ho, who has a fear of heights, to look at the transparent floor, prompting Kim Jun-ho to call it "workplace harassment," drawing bursts of laughter.

Upon arriving at Gohado, the members enjoyed the panoramic view of Mokpo from the observatory and kicked off the 'Solo Burden Game' with the cable car fare at stake. The members hatched a scheme to stick Lee Sang-jun with the solo bill, but Lee Sang-jun delivered an unexpected twist, declaring, "I will pay for all the expenses myself." Watching this unfold, Jang Dong-min expressed his astonishment, calling it an "over-the-top move."
