“When we first debuted, I couldn’t handle myself very well with the language, so I wasn’t able to live up to the responsibility of being a leader. Although there is still much for me to work on, I am much happier and I am able to do a lot more for the younger team members. Recently, I have a lot of solo activities and that has increased stress because I represent f(x). Being on shows has giving me a lot of experience and friends, but it also me feel that I need to improve myself much more. Thinking about this makes me a little depressed.”
