In the show 'Marriage Lesson,' Kang Soo-ji suspected Kim Il-woo and Park Sun-young.

On the broadcast aired on the 2nd by Channel A's 'Modern Man Life - Marriage Lesson' (hereinafter referred to as 'Marriage Lesson'), Kim Il-woo was seen inviting Park Sun-young to Chung-Ang University, his alma mater.

On that day, Kim Il-woo, who visited his alma mater with Park Sun-young, explained, "Sun-young previously mentioned wanting to experience a date in a crowded place," adding, "This is my alma mater. I came to Chung-Ang University. These days, it's the start of the new semester, and since there are many students, I wanted to let Sun-young, who graduated from a women's university, experience the feeling of being in a couple, so I came to my alma mater, Chung-Ang University."

Lee Seung-cheol asked, "Isn't coming to a crowded place a way to be recognized as an official couple?" to which Kim Il-woo replied, "When I'm with Sun-young, I can't help but feel a little proud," adding, "Every time we go on a date, I see her happy, and I want to make her enjoy herself."

As soon as the two entered the school, they visited a merchandise shop. It is a place that sells various goods, including department jackets and T-shirts. Park Sun-young said, "Oppa, what I want is couple shirts. Coincidentally, we wore white pants," as she matched a navy jumper to her pants.

Park Sun-young put clothes on Kim Il-woo and said, "You're cute," and Kim Il-woo, feeling a sudden youthfulness, looked at the 'C' printed on the clothes and said, "We're CC." Then Park Sun-young suddenly asked, "Wow, I wanted to experience being a couple in a women's university, but I couldn't. Oppa, did you?" Surprised, Kim Il-woo honestly replied, "I did," causing the panelists to gasp.

Amid the suddenly awkward atmosphere, Kim Il-woo said, "Just in case, take one of these, too," attempting to lighten the mood as he picked a junior jumper, which made everyone laugh.

As they walked around the campus, Kim Il-woo confessed about his past relationships, saying, "I wasn't necessarily a couple, but it seems we dated without making it obvious. Why would we walk around with our arms linked when we could meet at school?" At that moment, Park Sun-young unexpectedly linked arms with Kim Il-woo, who was surprised but smiled broadly.

Later, the two roamed around the campus like a couple and looked for the campus cafeteria. While waiting for their ordered food, a student asked, "Are you getting married?" which excited the studio.

Park Sun-young said, "Oppa, don't people congratulate you these days? I heard a lot of congratulations yesterday at the wedding venue," particularly recounting how Kim Il-woo was asked by Su-ji, "Doesn't Su-ji usually not talk about such things? Su-ji said, 'How is it going with Il-woo? I am looking forward to it. Are you two dating secretly like us?"

As the panelists in the studio began to suspect the two, Kim Il-woo joked, "It's not secret. It's already out there."
