Jo Ha Seul is a South Korean singer, dancer, former member of LOONA (이달의 소녀) and current member of ARTMS (아르테미스). She graduated from Sangwon High School. In October 2016, Blockberry Creative (블록베리크리에이티브) decided to debut a girl group through an 18-month long pre-debut project. She was the third to be revealed and released her single "Let Me In" in December 2016. After 4 members were revealed, she formed the sub-unit LOONA 1/3 with them and released the EP "Love & Live" in March 2017. She officially debuted in August 2018 as the group's leader, vocalist and rapper with their first EP, "[+ +]". In November 2022, member Chuu was removed from the group after winning a partial injunction against the agency to terminate her contract. The company blamed Chuu and cited an abuse of power as the cause for her removal. However, the remaining members filed an injunction to terminate their contracts three days after Chuu was removed. The agency even teased a comeback scheduled for January 2023 which was promptly boycotted by the fans and postponed indefinitely. In June 2023, her injunction was granted and she left the company. She signed with Modhaus (모드 하우스) who decided to create the group ARTMS. In June 2023, the group began several pre-debut projects. First, LOONA's former sub-unit, ODD EYE CIRCLE (now called ODD EYE CIRCLE+) was re-activated and released their EP "Version Up" in July. Then, she debuted as a soloist in October 2023 with the single, "Plastic Candy". Finally, the full group debuted in May 2024 with the album "Dall". (Source: MyDramaList) Watch drama online for free.
