Q: (Based on Korean age) you are now entering your 30s, what has changed?
JKS: Energy level has gone down (laugh) This is a joke. However since January this year, I felt a stronger sense of responsibility, and I have to work hard, yet nothing really changed. In my 20s, I was working hard, there is little time for myself nor time to relax. I turned 30 in August, it is important to recharge in order to excel in the drama I wish to act in. I need to be zealous during worktime, and fully relax during my personal time. I feel it is important to strike a good balance between the two.
