Krystal Jung Eyes (+(KR)ystal Eyes), the new Dimension of the group Triple S, handed out a special gift. According to their agency Mode House on the 22nd, Krystal Jung Eyes (Yoon Seo-yeon, Kim Soo-min, Chaeyeon, and Lee Ji-woo) released a music video of "Touch" on their YouTube channel at midnight. The members in the video melted the lovely uniform fashion and everyday life in the school, capturing the eye. The beautiful melody of Touch', the beautiful visual beauty, and the perfect performance, gave Krystal Jung Aizu a special charm. In addition to members Yoon Seo-yeon, Kim Soo-min, Chaeyeon, and Lee Ji-woo, Triple S's S14 Park So-hyun appeared. As a result, the original song Touch' was newly named Touch +', and Park So-hyun's sensational rap was added to the hot response of 'Wave (official fan name)'. Meanwhile, Krystal Jung Eyes recently released their first EP 'AESTHETIC' and announced their debut. The album's sub-track Touch' is a reprint of the girl group sound of the late '90s. It is nostalgic for those who remember the girls of those days who lived in Y2K, and fresh for those who know those days only as images of the Internet. Krystal Jung Eyes' debut mini album 'Esthetic', a triple-es unit created by fans' choice, can be enjoyed on the online music site.
