During an interview with Ilgan Sports, the actor admitted, "I have become more and more afraid about marriage and parenting. I think its because I am getting older. Of course, there will be a lot to learn, and I also know that the experience will help in my acting."
Gong Yoo continued, "Some day I will marry and become a father, but I should've already had 2 kids considering my current age. In fact, my friends are parents of elementary students, but despite my age, I am still very young [mentally]. Just by what I see from others around me, I can tell that getting married, creating a family, and having kids is extremely difficult. I think that's also why my younger, married friends seem more like hyungs to me."
