She revealed that she had a boyfriend in the past and they dated each other for around 300 days. �The MCs asked whether that was why she decided she would not date until she was in her 20s. �Kim Yoo Jung explained, "That's partly why, and this is a bit weird for me to say, but what I felt after trying a relationship was that at my age, it is hard to control my feelings by myself and, even more so, it's better to spend time on myself and my own development. I think it's right to date when you're older."

The MCs could not help but keep nodding at her wise words, showing that she was mature for her age.
