She said of herself, "Sometimes my frank way of speaking creates misunderstanding. People who know me say, 'You have to listen to what she has to say to the end.' However, I'm not the type of person to explain myself in every single misunderstanding."

As for compliments on her appearance, Sulli commented, "I feel good when I hear that I'm pretty. I also hear that I'm kind of strange, but I usually respond, 'There are a lot of strange people, but why me?' I don't dislike the comment, but I'm curious. I'm curious what others think of me. I'm confident that if people knew me, they wouldn't hate me. I also feel that I'll regret it if I don't make friends now, so I go up to them and say, 'Want to be friends with me?'"

On what she most regrets, the actress revealed, "In my 24 years of life, my regret is college. I wanted to go to college, but I couldn't go. I want to go to college for sure later on."
