Chuu (Hangul: 츄) is the tenth revealed member of LOOΠΔ and a member of its third sub-unit, LOOΠΔ / yyxy.

She was born as Kim Ji Woo (Hangul: 김지우) on October 20, 1999 in North Chungcheong, South Korea.

She debuted on December 14, 2017 as a member and subsequently released her solo single album "Chuu" on December 28, 2017.

Early lifeEdit

Chuu was born and raised in Chungju, Chungcheong Province, South Korea, with her parents and two younger brothers. She attended Saet-byul Elementary school and San-nam Middle school. Growing up, Chuu had always wanted to be a singer. However, she was not given support from her mother due to her familiarity with the difficulties of becoming a singer. Despite that, Chuu continued to pursue her dream with the approval of her father.[1]

In order to become a singer, Chuu applied and was accepted as a singer major at Hanlim Multi Arts High School in Seoul in 2015. Later, she became a trainee at FNC Academy in 2016.[2] Sometime after, she left FNC Academy and joined Music Works. It was also around this time that Chuu started her popular Instagram account. Wanting to further challenge herself, Chuu departed from Music Works to seek for a new agency. Although she auditioned for JYP Entertainment and YG Entertainment's "The Black Label", she was not accepted into either one of them.

On November 11, 2017, Chuu made her final post on Instagram before disappearing. Seemingly unrelated, a member of LOONA, named Yves, appeared in episode 230 of LOONA TV on December 6. A day later, the teaser for LOONA's 10th member was released. Not until days after the episode of LOONA TV, a fan of Chuu's noticed that Yves' phone had a sticker given to Chuu on her birthday two months before. As a result, many fans had predicted that the new member would be the well known 'Instagrammer' "Kim Ji Woo". These were later confirmed on December 13 when it was announced the new member was Chuu.[3]

On February 9, 2018 Chuu graduated from Hanlim Multi Arts School alongside Kim Lip.
