LOONA (LOOΠΔ – 이달의 소녀)

What are LOONA Members?

LOONA members are the individual performers comprising the South Korean girl group LOONA, stylized as LOOΠΔ, formerly managed by BlockBerry Creative. The group consists of twelve members who debuted between 2016 and 2018: HeeJin, HyunJin, HaSeul, YeoJin, ViVi, Kim Lip, JinSoul, Choerry, Yves, Chuu, Go Won, and HyeJu (formerly known as Olivia Hye). Each member received an individual solo debut before the full group formation, creating a unique pre-debut project spanning nearly two years. As of 2022, the active lineup comprises eleven members following Chuu's removal from the group on November 25, 2022.

Each member possesses distinct representative attributes that form their individual identity within the group. These attributes include designated colors, animals, shapes, flowers, and in some cases, fruits and specific locations. For instance, HeeJin represents vivid pink with a rabbit symbol and a square shape, while Kim Lip embodies red with an owl symbol and a circular shape. HaSeul, the group's leader, holds green as her representative color with a white bird as her animal symbol. Similarly, ViVi represents pastel rose with a deer, YeoJin embodies orange with a frog, JinSoul carries blue and black with a blue Betta fish, Choerry represents purple and white with a fruit bat, Yves holds burgundy with a swan, Go Won carries Eden green with an Emperor butterfly, and HyeJu represents silver and black with a wolf.

The members are organized into three distinct sub-units that debuted separately before the full group formation. LOONA 1/3 comprises HeeJin, HyunJin, HaSeul, and ViVi. ODD EYE CIRCLE includes Kim Lip, JinSoul, and Choerry as members. The third sub-unit, yyxy (read as "youth youth by young"), consists of Yves, Chuu, Go Won, and HyeJu. This sub-unit structure allowed members to showcase different musical styles and concepts, with each unit maintaining its own distinct sound and visual identity within the broader LOONA universe.

LOONA Sub-units and Member Groups

LOONA 1/3

LOONA 1/3 debuted on March 12, 2017, as the first sub-unit comprising HeeJin, HyunJin, HaSeul, and ViVi. The extended play Love & Live accompanied the debut on March 13, 2017, with promotional activities on SBS's Inkigayo. The sub-unit's name derives from representing one-third of the group's total membership, with YeoJin symbolically representing the slash mark between 1 and 3. On April 27, 2017, a repackaged edition titled Love & Evil released with the single "Sonatine".

The sub-unit's musical direction centers on soft love concepts, exploring themes of first love excitement and heartbreak. Within the LOONA universe, each member possesses a representative location, such as HeeJin representing Paris. Love & Live reached number 10 on South Korea's Gaon Album Chart, while Love & Evil peaked at number 24. The production budget for LOONA 1/3 reportedly reached 4 million dollars, with music video filming locations spanning New Zealand and Hong Kong.

LOONA Odd Eye Circle

Odd Eye Circle, consisting of Kim Lip, JinSoul, and Choerry, debuted on September 21, 2017, with the extended play Mix & Match and the single "Girl Front". The sub-unit began promotions on Mnet's M Countdown following their debut. On October 31, 2017, the repackaged edition Max & Match released with three additional songs, including the lead single "Sweet Crazy Love". The EP reached number 16 on the Gaon Album Chart, while the repackaged version peaked at number 7.

The sub-unit employs a girl crush concept addressing fondness, seduction, playfulness, romance, and intimacy. Each member possesses unique supernatural abilities within the LOONA universe, such as Kim Lip's time travel capability. Following successful contract terminations with BlockBerry Creative on January 13, 2023, the trio signed with Modhaus on March 17, 2023. Modhaus filed a trademark application for the Odd Eye Circle name on March 27, 2023. On July 12, 2023, the sub-unit released their second EP with the lead track "Air Force One," co-written by Kim Lip, marking their first release in nearly six years.

LOONA yyxy

LOONA yyxy, an abbreviation for "youth youth by young," debuted on May 30, 2018, with the extended play Beauty & the Beat. The sub-unit consists of Yves, Chuu, Go Won, and HyeJu. The title track "love4eva" featured Canadian musician Grimes, who collaborated after fan requests. The extended play achieved number 4 on the Gaon Album Chart.

The sub-unit's concept revolves around an Eden dimension where members experience love, hurt, and brokenness while capturing moments of youth. Each member represents a specific emotion and fruit, such as Yves embodying faith with an apple. The name "yyxy" references a neanthropic chromosome distinct from standard XX or XY chromosomes.

What Happened to LOONA Members?

Contract Disputes with BlockBerry Creative

Contract disputes emerged when Chuu filed a provisional injunction to suspend her contract with BlockBerry Creative in January 2022, which the court accepted. Following this ruling, Chuu remained notably absent from promotional activities, including the group's first world tour, though BlockBerry cited scheduling conflicts at the time. On November 25, 2022, BlockBerry Creative announced Chuu's removal from the group, alleging violent language and power abuse toward staff. Chuu responded via Instagram, stating she had not done anything shameful. The Seoul High Court ruled in Chuu's favor in August 2023, officially nullifying her contract and ordering BlockBerry to bear lawsuit costs. BlockBerry appealed for a second trial, but the ruling remained unchanged as of March 8, 2024.

Members' Legal Battles

On November 28, 2022, nine members excluding ViVi and HyunJin filed injunctions to terminate their exclusive contracts. BlockBerry Creative denied these reports, calling them groundless. The Seoul Northern District Court ruled on January 13, 2023, granting preliminary injunctions to HeeJin, Kim Lip, JinSoul, and Choerry due to contract terms identical to Chuu's. Five members—HaSeul, YeoJin, Yves, Go Won, and HyeJu—initially lost their cases because amendments made to their contracts in 2021 resulted in denied injunctions. On February 3, 2023, ViVi and HyunJin filed for contract suspension. These two members received preliminary injunctions on May 9, 2023.

The remaining five members won their lawsuit on June 16, 2023, when the court confirmed their exclusive contracts had no effect. The court accepted their secondary claim for contract termination after members notified BlockBerry in 2023 that the company had transferred contractual rights to a Japanese entertainment agency without prior written consent. BlockBerry filed petitions with Korean entertainment associations to ban former members from activities in South Korea.

Group's Indefinite Hiatus

BlockBerry Creative postponed the comeback album "The Origin Album: 0," originally scheduled for January 3, 2023, indefinitely on December 22, 2022. Pre-order sales dropped by 98% following fan boycotts protesting Chuu's removal and member mistreatment. The company acknowledged that comeback activities would be meaningless while concerns about member circumstances remained unresolved.

Where Are LOONA Members Now?

Loossemble (CTDENM)

Following their contract terminations, five members formed Loossemble under CTDENM, debuting with their self-titled EP on September 15, 2023, in New York City. The quintet released three extended plays during their tenure: the debut Loossemble with lead single "Sensitive", One of a Kind on April 16, 2024, featuring "Girls' Night", and TTYL on September 2, 2024. The group conducted two United States tours, including the Loona Assemble: The US Debut Ceremony Tour spanning September to October 2023 and the Up_Link Station US Tour across nine cities through October 2024.

On November 29, 2024, CTDENM announced the termination of Loossemble's exclusive contract. Member HyeJu assured fans on messaging platform Fromm that the members would "still be seeing each other". Notwithstanding their stated intentions to continue as a group, complications arose with potential new agencies. Go Won revealed on May 27, 2025, through livestream that issues emerged with a company under discussion, indicating the group was starting over again. HyunJin announced on June 5, 2025, that she would manage her own activities through Triangle ENM. The same day, YeoJin released her digital single "Dancing In The Dark".
