On the broadcast of SBS variety show "My Ugly Duckling" aired on the 2nd, singer Sunmi appeared as a special MC. Sunmi attracted viewers' attention by showcasing a neat daughter-in-law look on the show. Shin Dong-yup asked, "You came dressed as a daughter-in-law today, but whose daughter-in-law are you?" In response, Yoon Min-soo's mother replied, "I think Yoon Min-soo will be excluded," causing laughter.

Kim Seung-soo's mother emphasized, "Our son is still single. Our son looks young." Sunmi reacted, "What does age matter these days?" However, when Seo Jang-hoon said, "Kim Seung-soo was born in 1971, so there is about a 25-year age difference with Sunmi," Sunmi expressed surprise, saying, "He's the same age as my mother." She then joked, "Being the same age as my mom is a bit awkward," drawing laughter.

Sunmi also spoke about her views on dating. She said, "The number of times I've dated can be counted on one hand," and added, "When I date someone, I date for a long time. I feel that the 'getting to know each other' phase is emotionally draining, so when I'm sure I really like someone, I bulldoze forward and say, 'I like you. Don't think about just flirting.'" This shows Sunmi's serious attitude toward relationships.

Regarding her ideal type, Sunmi was specific. She said, "I like a certain face shape. One that is smooth without sharp edges, a more angular style. A face like Matt Damon's, and among soccer players, I like Kevin De Bruyne's face shape." When Shin Dong-yup mentioned, "Seo Jang-hoon is that kind of style too," Sunmi smiled and said, "I saw photos of senior Seo Jang-hoon when he was a basketball player, and he had the ideal face."

Sunmi revealed that she has raised two younger brothers and has taken on a motherly role. About expressing affection with her brothers, she said, "When we hang up the phone, we say 'I love you.'" Shin Dong-yup then asked, "Can siblings really say that to each other?" and suggested an impromptu phone call. When Sunmi said, "Dong-a, I love you," her brother immediately replied, "Yeah, I love you," showing their warm sibling relationship.

Sunmi showed a cool attitude about the age difference but felt awkward when it came to being the same age as her mother. Her reactions on the show brought laughter to viewers and revealed Sunmi's genuine charm. Through the broadcast, Sunmi honestly expressed her thoughts and feelings, gaining empathy from many.
