On ChannelA's "Groom's Lesson 2," Kim Sung-soo and Park So-yoon step up as models for a charity fashion show, and the process of meeting Hanbok designer Park Sool-nyeo to prepare custom formal wear is revealed.

In this episode, the two visit Park Sool-nyeo's Hanbok shop to prepare for the fashion show. Park Sool-nyeo warmly welcomes them and offers encouragement, saying, "You seem like you'll live happily if you get married." In particular, she shares her own experience of marrying her husband just three months after meeting him, and promises that if the two get married, she will personally make not only Hanbok for both mothers but also her own, creating a heartwarming moment. She also prepares bedding gifts for both families, delivering deep emotion.

In the studio, Lee Seung-chul, Tak Jae-hoon, Song Hae-na, Kim Yo-han, and Lee Hyun-yi watch the couple's preparation process and unanimously say, "It feels like they are actually about to get married." Kim Yo-han and Lee Hyun-yi offer words of support, saying, "You could just get married while wearing the fashion show clothes."

On this day, Kim Sung-soo made full use of his past experience as a Hanbok fashion show model, actively supporting Park So-yoon. He personally tied the sash of her formal wear and practiced runway poses together, demonstrating his veteran expertise.

The couple's first joint fashion show stage and their entertaining visit to the Hanbok shop will air on ChannelA's "Groom's Lesson 2" on the 24th at 9:00 PM.
