Although she works as a part-time model, Krystal is not really interested in photography. One day she joins Sulli and Jiyoung to go to a photography exhibition at the town hall. Being a straighforward and honest person she is, she expresses her "not-so-good-to-hear" opinion about a photo that she finds very weird. Little did she knows that the real photographer of the photo was listening to all her words.
