"I wanted to go for a new look so I even cut my hair," she added, describing her bold move. The reason why she decided to take on various roles was, "I feel that I might get tired of playing the same role every time."

Krystal also said, "It's all still a learning process for me. I think I'll have more time to present more dynamic works in the future as I get older. For right now, I get nervous, yet wish to do my best in order to illustrate a level of perfection."
