When asked what made her hungry for acting, she pointed out her role in the drama 'School 2013', explaining she learned the fun of being an actress. She was then asked about her twin sister Hwayoung, and Hyoyoung answered, "There are times that we take turns getting sick maybe because we're twins. These days, because we live separately, it's not as bad. We may be twins working in the same industry but we're completely different, so I don't think it's a bad thing at all. I feel like it's something even better than having a friend. We have different thoughts, so our advice to each other is very different."
Hyoyoung then stated about her ideal type, "I like people who have a lot of thoughts, and people from whom I can learn from. I don't look at visuals. I only look at personality compatibility. I don't care about outer appearances or age in the least. But I do think I'd like someone who's good at sports. I think because my hobbies are working out and leisure sports, we'll have something in common."
She wrapped up her interview with, "I'm a person who works hard each day to live well, so please watch me for a long time to come... What I'd like to say to my fans is that I'm so thankful they've waited for me for such long time, and I want to greet them through different pieces soon."
