Producer Park Cheol-hwan, the creative force behind Channel A’s popular dating reality show “Heart Pairing,” recently offered an in-depth look into the complexities of the program, which aims to guide young people serious about marriage towards finding a life partner. In an interview held on May 7th in Sangam-dong, Mapo-gu, Seoul, Park candidly discussed challenging casting decisions, the show’s evolving philosophy distinct from its predecessor “Heart Signal,” and his earnest hopes for the couples formed.
The “Harsh” Reality of a 15-Year Age Gap: The Case of Changhwan
One of the most significant talking points of the season revolved around participant Changhwan, born in 1984, and his noticeable age difference with other contestants, particularly Ji-won, who was 15 years his junior. “The most honest feeling I had was that we shouldn’t have proceeded with the program given Changhwan’s age difference,” Park confessed. He elaborated on the initial experimental approach, stating, “When we discussed launching a new season, we considered trying out this level of age gap as an experiment—but I realized that’s not something we can do.” Park acknowledged the inherent difficulty, adding, “Changhwan is definitely charming, but unless the male cast is composed of people in a similar age range, no matter how attractive he is, it becomes very difficult for him to withstand the situation itself.”
This dynamic, Park explained, fostered a challenging environment. “It becomes a battle of self-esteem. We created a harsh environment for him,” he admitted. The producer even revealed Changhwan’s own perspective: “Changhwan even said this felt like ‘a job scam.’ And I think he had every right to say that. That was our shortcoming.”
Despite the eventual difficulties, Changhwan was an early and appealing choice for the show, which was conceptualized with the premise of ‘pairing means marriage.’ “Changhwan was actually the first person we cast,” Park shared. “When we first conceptualized the show… I met him. He was incredibly impressive. He had a great job, and when I first met him, he reminded me of actor Lee Jin-wook. Above all, despite his looks and aura, he gave off a very homely and family-oriented vibe.” This initial impression led Park to keep Changhwan on the candidate list. “I wanted to work with Changhwan… I couldn’t let him go. I was curious about the sincerity and story he could bring to the show.”
Park confessed he agonized over the casting until the end, holding onto a belief: “I had faith. With this level of charm, I thought he might appeal to women in their early to mid-30s. His pairing book was adorable. I thought if someone had a soul like his, maybe the age gap could be overlooked.” However, the outcome was unexpected. “But I didn’t expect him to get paired with the youngest participant,” he added. “From Italy onward, I was very surprised and taken aback,” referring to Changhwan and Ji-won’s initial romantic connection that later drifted apart after the age gap became a focal point.
Navigating Past Appearances: The Casting of Ahn Ji-min
Another complex casting decision involved Ahn Ji-min, who had previously appeared on the show “Love Catcher.” “I kept agonizing over Ahn Ji-min’s casting right until the very end because he was previously on Love Catcher,” Park stated. His concerns stemmed from potential preconceived notions or misunderstandings. However, the interview process swayed him. “During the interview, I really liked Ahn Ji-min. In my heart, I wanted to bring him on,” Park said. “When I interviewed him, I didn’t have high expectations. I just had a good impression of him from Love Catcher, so I invited him. But I kept wondering—despite the concerns and potential misunderstandings, is he someone I could really bring into the show?”
What ultimately convinced Park was Ahn Ji-min’s grounded personality. “What surprised me most during the interview was how grounded he was. You could say his feet were firmly on the ground—he was realistic. You’d expect someone like him to go full-on influencer mode, but he actually continued working at a company while changing jobs,” Park noted. Ahn Ji-min expressed a genuine desire for marriage, citing his current life stage. “Ji-min said he has strong metacognition. He said this is the kind of work that suits him. He told me he really wants to get married now, that he’s past the ideal timing and feeling the urgency.” Park added, “At his age, he said it’s hard to meet people naturally. He said he’d go two to three months without any weekend plans and that blind dates aren’t easy. Hearing things like that made him seem very real… Despite the concerns, I thought that if he joins the show and finds someone, he’ll be sincere about it. But I still had to think it through carefully because misunderstandings were possible.”
Casting Philosophy: Urgency, Sincerity, and High-Profile Participants
“Heart Pairing” often features contestants who are notable in their respective fields. Park explained the rationale: “In a show like this, people only put in their best effort when the other participants are the kind of people you’d never run into in everyday life… We chose participants who would give off the feeling of being someone you could only meet through this show—that sense of urgency is key.”
This search for sincerity extends to younger participants as well. Speaking about Haneul and Ji-won, Park said, “They’re young. During interviews, you can tell who’s seriously thinking about marriage and who isn’t.” He highlighted Ji-won’s maturity: “For example, Ji-won left a strong impression. She’s young, but I wanted to see how she would view someone through the lens of potential marriage. She said her dream was to be in a relationship for three years. She wanted to experience that in her twenties, but now feels it’s already too late. She told me that if it’s not a relationship headed toward marriage, she’s not interested. That sincerity really struck me… She’s someone who wants happiness that comes from a healthy, tangible life, and that made me trust her.”
As for Haneul, a dancer-turned-model, Park noted, “Despite appearances, her devotion in relationships was impressive. She’s the type who doesn’t overcalculate. Since her mid-20s, she hasn’t engaged in unserious relationships. Whenever she dates someone, she’s genuine.” He added, “She didn’t just start as a model—she danced for a long time. That kind of background brings a certain life experience into the modeling profession, which made me feel she’d be a good fit for the show.”
A New Chapter in Dating Shows: Beyond “Heart Signal”
“Heart Pairing” positions itself as a “pre-marriage dating diary full of both romance and reality-check for young people who want to get married,” focusing on individuals earnestly seeking a life partner rather than casual flings. Park, who also directed “Heart Signal,” drew a distinction between the two. He acknowledged the volatile nature of on-screen romances and their aftermath, stating, “There are many breakups that happen while people are watching Heart Signal. Some couples are truly unfortunate.”
With “Heart Pairing,” the intention was to cultivate deeper, more stable connections. “I created the program with the hope that there would be long-lasting couples—ones that actually go on to get married,” Park said. “I wanted to offer the kind of environment where people could grow attached to one another, like a ‘contract relationship.’ In Heart Signal, even if they want to form bonds, their feelings get pulled in different directions—that’s how young love is,” he explained. “But in Heart Pairing, I introduced a kind of ‘contract dating’ that says, ‘If there’s someone you genuinely want to get to know, go ahead and try.’ I wanted them to be able to express themselves without interference, to explore freely and deeply.”
The proliferation of dating shows has, according to Park, led to a demand for more intense content. “There are so many dating shows now,” he observed. “As similar stories keep repeating, more stimulating and entertaining situations and setups have started to appear.” He felt a need to return to the core of romantic connection: “When dating shows first emerged, there was a dopamine rush—the thrill of romance. But it’s been a while since we’ve seen a show that truly delivers that tingly excitement of falling in love.” “Heart Pairing” was conceived from this desire to portray romance “more intimately and sincerely.”
“I didn’t want to just show setups and events within the format of a dating program—I wanted to dive into emotional clashes and deeper connections,” Park emphasized. “I felt like we needed to move beyond just ‘something casual’ and into actual romantic relationships. Heart Signal delivered that youthful vibe, but Heart Pairing aims to show something deeper.” This direction was also informed by feedback from potential cast members who were looking for a more serious commitment. Park revealed that some declined, saying things like, “I should be thinking about marriage, and I don’t think it would be right to come on a show that feels like young people just dating,” or “I need something more serious.” He reflected, “These are people who are genuinely thinking about the next step—from dating to marriage—and I realized that Heart Signal wasn’t the place to explore that. That’s when I knew their stories needed a different platform.”
Hopes for Marriage and a Promising Future
Looking ahead, Park is optimistic about the outcomes. When asked about a potential spinoff for a couple that marries, he replied, “I’d love to, if someone does get married. But the cast members are really busy. Even scheduling a poster shoot was difficult due to their full-time jobs.” He also teased the show’s conclusion, saying, “You’ll want to become even more emotionally invested.”
“Heart Pairing” has clearly struck a chord with viewers. The show ranked 4th on Good Data Corporation’s Fundex “TV Non-Drama Buzz” chart and 6th on the “TV-OTT Non-Drama Buzz” chart for the 4th week of April 2025, marking its second consecutive week in the top 10. It continues its record-breaking run, setting new personal bests for six consecutive weeks.
“Heart Pairing” airs every Friday at 10:50 p.m on Channel A.
