Youth youth by young! Hello, we are LOOΠΔ / yyxy~


yyxy (Hangul: 이달의 소녀 yyxy), stylized as LOOΠΔ/yyxy, is the third and final pre-debut sub-unit of the girl group LOOΠΔ. They debuted with members Yves, Chuu, Go Won and Olivia Hye on May 30, 2018 with the mini-album Beauty & The Beat.


The unit's Korean name is pronounced Idalui Sonyeo Wai-wai-bai-wai (Korean: 이달의 소녀 yyxy) from the Sino-Korean root meaning "Girl of the Month", combined with the made-up neanthropic chromosome "yyxy".

Unit ConceptEdit

yyxy is composed of four girls who denied Eden, talking about the ego of the youth. Being in love, hurt, broken, but still stepping forward, they capture moments of youth to complete an ego. They express that ego is falling in love with themselves, and that they must first love themselves before loving others. They declare neanthropic chromosome yyxy, different to xx or xy chromosomes.

Mini albumsEdit


  • yyxy's first stage performance was at their own event: LOOΠΔ Cinema Theory: Line & Up. This is considered extremely unique and unheard of as debut stages for groups are usually performed on live TV stages such as Inkigayo or M Countdown, and not at their own events.
