'My Little Old Boy' Jin Se-yeon Says Choi Jin-hyuk Was Her First Kiss Partner: "I Just Did My Best"

On the February 15 episode of SBS’s "My Little Old Boy," actor Jin Se-yeon appeared as a special MC.

“I’m not super openly cutesy, but my tone changes around people I like,” she said, sending a heart gesture to the Mom-vengers and drawing laughs.

Jin shared that, among the "My Little Old Boy" sons, Choi Jin-hyuk was her first kiss partner. “I acted with Jin-hyuk oppa when I was transitioning from 19 to 20. When I was 19, it was more like a light peck, but as soon as I turned 20, the script described it as being stronger than before. The writer said it felt like a ‘seal being lifted’ now that I was an adult,” which drew laughter.

The moms then asked whether the scene was actually intense. Jin Se-yeon shyly replied, “I had no experience, and since it was a daily drama, the level wasn’t that intense. So I just did my best.”

She also clarified she’s not someone who’s never dated. “In my early 20s, I had no dating experience, so people called me ‘single forever.’ Even after I dated later on, that never made the news,” she explained.

When she mentioned she currently plays Kim Seung-soo’s daughter in her latest drama, the MCs cracked up and made fun of Kim Seung-soo: “Choi Jin-hyuk is her first kiss partner, but Kim Seung-soo, you are her dad―not even a dad’s friend, actual dad!”
