On February 12, Son Suk-ku appeared on actress Yoo In Na's YouTube show "You in Radio."
While talking about relationships, Yoo In Na and Son Suk-ku discussed how long the unofficial dating phase should last.
Son Suk-ku said, "When I was younger, I thought that stage should last about a month. But now, I'd say it'd be more like three to six months."

Reminiscing the past, Son Suk-ku shared, "She was my first love, and as far as I know, I was hers too."
Then he revealed something unexpected—she was from a super rich family.
"At the time, I had no idea just how wealthy she was. She was a senior at my school, and I was a sophomore. She was from Thailand."

He stated, "I randomly came across her social media and saw a photo of her standing in front of a waterfall. Then I found out… that waterfall was in her backyard!"
Laughing, he added, "That's when it hit me—she was living in a whole different world. And I finally understood why her older brother didn't like me so much."
Son Suk-ku attended St. John's Preparatory School in Minnesota, the United States.
