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.
