The article reveals Yuna's specific goals for her comeback, and detailed plan for the future competitions.
She states that 4CC is not in her competition plan for this season; probably due to the conflict of schedules between 4cc and PyeongChang 2013 Special Olympics for which she is the ambassador.

“I’m a bit worried because I took a season off… no actually I’m worried a lot (laughs). I’m working hard. I want to do my best so I can go to the Olympics with my fellow Korean skaters. I want to earn at least 2 tickets to the Games.”
When asked “When was the most difficult time during your skating career?” she replied, “During my 16 years of skating, joy felt over a great performance or result was short-lived. The struggle starts the very next day when training resumes so I think each day is difficult.”

Her happiest moment she recalls was “After the free skating at the Olympics just before the scores were announced. I was just happy that everything was over. I felt relieved,” she said.
