Introduction to yyxy
" 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&thebeat.
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”.
yyxy is composed of four girls held in a separate dimension called Eden. In “love4eva”, it’s revealed that if they eat their individual Forbidden Fruit, they are expelled from Eden. They soon feel trapped and adventurous, so Yves convinces Chuu and Go Won to eat their forbidden fruit and escape with her. Olivia Hye also wants to go but is not brave enough to eat her fruit. They leave without her.
Olivia eventually eats her fruit and tries to follow them, but becomes lost and angry. She knows that Yves plans to create a new dimension, and decides to destroy it out of anger at being abandoned by her friends.
This journey is about the ego of the youth. Being in love, hurt, broken, but still stepping forward, the girls 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.
