Seong Dong-il's 18-year-old daughter Seong-bin has grown into a young woman: "I supported Yoon Jumo from the start"

Actor Seong Dong-il's 18-year-old daughter Seong-bin appears all grown up as she joins her father and older brother Seong-jun for a cheerful gathering with Yoon Jumo, the persona of Chef Yoon Na-ra, on the YouTube channel "Sul Bitneun Yoon Jumo," which is set to be released on June 19.

Seong-jun, who graduated from a science high school and is now a second-year student in the Department of Civil and Environmental Engineering at Hanyang University, and Seong-bin, a high school senior majoring in contemporary dance, both show a notably mature side. Their appearance marks a clear contrast from the younger images many viewers remember from the family variety program "Dad! Where Are We Going?"

At first, Seong Dong-il and Seong-jun spend a pleasant time with Yoon Jumo. Seong-bin then arrives later, opening the door to Yoonjudang and stepping into the gathering.

Seong-bin appears so changed that Seong-jun jokingly says, "I didn't recognize her either." The cute, spirited tomboy image she once showed on "Dad! Where Are We Going?" is nowhere to be found, and she enters as a young woman who has grown up quickly. When Seong-bin becomes shy because, unlike in the past, she now feels awkward in front of the camera, Seong-jun teases her by saying, "I'm not used to this Bin-i."

Seong-bin explains that she had been attending a general high school before transferring to an arts high school, where she is now in her third year. "I took a taxi by myself and submitted my application to the arts high school just a few hours before the deadline," she says. "My whole family tried to stop me." Seong Dong-il recalls his feelings at the time, saying, "Back then, I was angry because Bin-i did what she wanted," admitting that he once disapproved of his daughter's decision.

Seong-bin also reveals her affection for Yoon Jumo. "I watched all of 'Culinary Class Wars 2' from the beginning to the end," she says. "I supported Yoon Jumo from the start. Every time she made it through, she cried, and it really moved me." Her confession of fandom touches Yoon Jumo.

Seong Dong-il jokingly shows a bit of jealousy, saying, "She has never watched any of her dad's dramas." Even so, he expresses special affection for Seong-bin. "Unlike Jun or our youngest, Yul, she has always expressed love the most, both then and now," he says. "I have high expectations for Bin-i. She does things no one else would think of."

Asked about "Dad! Where Are We Going?," a program that is still talked about today, Seong-bin shares her discomfort honestly. "Now it is a little embarrassing," she says. "New friends I meet sometimes say, 'I watched the videos.' We are not even that close yet, but the other person already knows all my embarrassing sides. It is not as if those are only pretty memories, is it?"

Seong-jun says he also struggled in a similar way when he was young, but has become more comfortable with it these days. "I had many good memories with Dad, but I also had so much fun playing with the other kids who appeared with us," he says. "Minguk hyung is 22 now. Even if I don't remember anything else, I remember Minguk hyung crying." With that, he shares the most memorable anecdote from his memories with Minguk.
