A solo camping trip, where Kim Yo-han and Shin Sung engage in a playful battle of wits as close friends, will be revealed on Channel A's variety show 'Groom Class 2.'

In this broadcast, Kim Yo-han meets Shin Sung and candidly shares that his recent romantic fling has come to an end. Shin Sung also shares his own experience of having a fling during the first season of 'Groom Class' three years ago that did not blossom into a relationship, only for the other person to get married six months later. When Kim Yo-han asks how he felt at the time, Shin Sung pauses to think before carefully sharing his inner thoughts. The two continue their friendly diss battle, exchanging jokes such as "Are you crying right now?" and "Are you suggesting we start something now?"

Before the camping trip, the two boost their motivation, declaring that "today is a friendly competition." They also bicker as they set various rules, including "Don't send separate DMs behind each other's backs to someone you're interested in" and "No appealing to charm by spiking a volleyball or singing."

At the campsite, Song Hae-na and Park Eun-hye join in, livening up the atmosphere. Kim Yo-han and Song Hae-na, knowing each other well, elicit laughter with their use of sarcastic banter. Meanwhile, although Shin Sung is meeting Song Hae-na for the first time, he shows his manners by yielding the electric fan breeze to her and helping prepare the ingredients, expressing his interest.

During the camping cooking showdown, Kim Yo-han presents grilled crab while Shin Sung prepares aged-kimchi spicy braised chicken, both striving to capture the women's hearts. In the process, rivalry, jealousy, and a hidden tug-of-war unfold over Song Hae-na.

The four share a conversation where they bond over their shared experiences as singles, saying, "Most of our friends have families of their own, so it gets lonely when there is no one to reach out to."
