On Channel A's 'Groom's Class 2,' Kim Yo-han and Oh Yeon-hee went on a date to check their compatibility in celebration of the 100th day since their first meeting.

The place they chose was a charcoal kiln sauna that Kim Yo-han frequents. The two shared a meal with sauna snacks such as baked eggs, sikhye, and cup ramen. During the meal, upon hearing that Oh Yeon-hee likes jjajang ramen, Kim Yo-han showed his affectionate side, saying, "Come to my house on Sunday, I'll make jjajang ramen for you."

In the 'flower bath,' the hottest bath in the sauna, Kim Yo-han attempted some friendly flirting, saying, "We're the only two here—should we kiss?" Watching this scene, studio mentors Lee Seung-chul, Tak Jae-hoon, and Song Hae-na asked, "So did you two kiss?" Kim Yo-han answered with a meaningful smile, saying, "I'll make no comment."

Afterwards, saying that synergy between a married couple is important, the two visited a fortune teller to find out whether they could have a positive influence on each other. The fortune teller interpreted Kim Yo-han's fortune as being blessed with great fortune, and Oh Yeon-hee's as kind-hearted and popular. However, during the reading, the fortune teller made a serious expression, saying, "Can I say this? There's a problem."

Meanwhile, Oh Yeon-hee said she recently went on a trip to Vietnam with her family, and that during the trip she talked about Kim Yo-han the most. In response, Kim Yo-han asked Oh Yeon-hee what they had talked about on the trip. In addition, Kim Yo-han expressed his determination to have a saju (Four Pillars) reading focused on marriage done properly.
