On the June 5 installment of Mnet's 'Dirty Talk,' Rainbow's Jisook brought up one instance when she misjudged somebody's personality, hence the term "wearing colored lenses."�

She said, "I thought Krystal would be a cold person, but I ran into her at a bingsoo (shaved ice dessert) shop in a department store and she greeted me first cheerfully. Seeing her like that, I wondered if I had looked at her through colored lenses."

This had previously been discussed by both Krystal and Jessica on their reality program, but most fans seem to know by now that the two are actually the sweetest, just a little bit shy!
