StayC (Sumin, Sieun, Isa, Seeun, Yoon, and J) released a behind-the-scenes video of the music broadcast of the title song "Colored Glasses" of the first mini-album on its official YouTube channel on October 26th.

The released video shows StayC relaxing in their own way ahead of the last music show stage of "Colored Glasses." The lovely visuals of the six members filled the screen and gave a pleasant smile.

StayC led the video to a variety of topics, such as introducing the last stage styling or practicing ending poses. From J's accessories to Sieun's lenses and Yoon's hairstyling, it delivered a variety of behind-the-scenes stories contained in music show activities, adding to fans' curiosity and special fun.

STAYC, who returned from the last performance, said, "We prepared hard for this activity.” "It doesn't feel real to hear that the activities are ending like this," they said, expressing their bitter and relieving feelings. The group also said, "The most regrettable thing is that I couldn't meet Sweet (fandom name)."I hope we can meet during the next activity," they said to their fans.
