Yoo In-na mentioned IU's remarks about Park Hae-joon. On the 6th, a video titled "Park Hae-joon who does everything without hesitation even when things go wrong" was posted on the YouTube channel 'Yoo In Radio.' Park Hae-joon played the role of Geum-myeong in the Netflix series 'Trickster,' where he acted as the father to IU. On that day, Park Hae-joon said during his first meeting with Yoo In-na, "Geum-myeong (IU) is such a close friend. I found out about this channel then and started watching it, and since you invited me like this, well, she's my daughter's friend, so I wanted to see her."

In the conversation with Yoo In-na, Park Hae-joon said, "I thought I made a good friend, so I came out," and facing the camera, he expressed his determination, saying, "Even if the 'Stop' people are this boring and silly, I will make it fun." Yoo In-na conveyed that IU said about Park Hae-joon, "Everything she says is like an ideal type for all of us." Park Hae-joon showed surprise at this remark and shyly said, "Well, it's not bad anyway."

Yoo In-na asked Park Hae-joon, "You graduated from Korea National University of Arts. But I heard your nicknames were 'Korea National University of Arts 2nd generation Jang Dong-gun' and 'Italian sculpture.' Is that true?" Park Hae-joon explained, "No one has ever called me 'Korea National University of Arts 2nd generation Jang Dong-gun' or 'Italian sculpture.' I think those keywords were distorted from an article."

Looking at Park Hae-joon's past handsome photos, Yoo In-na said, "Looking at this photo, I can't help but believe it. Do you remember this photo? Is this really you?" Park Hae-joon recalled, "That looks like a waiting room at a performance venue. That day, I had a severe hangover, so I was holding my head. But this photo was heavily edited. I've seen this photo a lot, but my face is red, so maybe the alcohol hadn't worn off. I had to practice, but I was like this." Yoo In-na admired Park Hae-joon's visuals, saying, "Could you grow your hair a little? You're so cool. You're like Terius himself."

During the broadcast, Park Hae-joon revealed behind-the-scenes stories about acting with IU. Yoo In-na asked IU, "You had so many crying scenes. Wasn't it hard?" and IU replied, "I cried automatically whenever I saw my dad (Park Hae-joon)." Park Hae-joon said, "Everyone I meet on the street looks at me pitifully and calls me 'father,'" adding, "That felt really good."

When Yoo In-na asked about Park Hae-joon's family's reaction, he said, "My parents were very proud," and added, "People contacted me a lot during 'The World of the Married,' but they said this is the first time they've received such a good response." He confessed, "After this work, I heard people say I had done all my filial duties," and said, "Rather, after the work ended, I felt I should be better to my parents."

Park Hae-joon also shared his two sons' reactions. He said, "The kids couldn't watch for more than 30 minutes," and "They calculated the time and asked, 'Can I watch what I want instead of this?'" He added, "I had limited their TV watching time, so I think they asked because they couldn't spend that time on my work."

This broadcast, containing honest stories about Park Hae-joon's acting and family, attracted great interest from viewers. The cheerful conversation between Yoo In-na and Park Hae-joon brought joy to many.
