Choi Yujin, a member of Kep1er, has captured fans' attention with a new concept image.

Recently, Choi Yujin posted a photo on her personal SNS with the phrase "CRACK CODE Zip." In the revealed photo, she is seen slightly tilting her body while staring directly at the camera, wearing a transparent long-sleeve blouse layered over a black short-sleeve T-shirt. Her long hair naturally flowing down creates a chic and mysterious atmosphere. In another photo, she shows a different charm by wearing a black top and necklace, raising her arms above her head and looking to the side.

This image release is part of the "CRACK CODE" project, which follows Kep1er's recently released new song "KILLA," raising expectations by hinting at the members' unique concept transformations.

Meanwhile, Kep1er is currently undergoing legal procedures in response to the demo track leak issue alongside their new song promotions. The agency has acknowledged the demo leak and announced a firm response. Currently, Kep1er continues active domestic and international activities while communicating with fans.
