Blockberry Creative ostensibly had a good thing going when it created the K-pop girl group Loona, but severe mismanagement resulted in all 12 members of the group leaving the company. However, all of the members still support each other, and indeed, many of them even still promote together. Such is the case with the ARTMS project at Modhaus, which reunited JinSoul, Kim Lip, and Choerry as Odd Eye Circle once again, in addition to bringing on Heejin and, later, Haseul. Odd Eye Circle redebuted in ARTMS on July 12, 2023 with Version Up and lead track “Air Force One,” while Heejin redebuted in ARTMS on October 31, 2023 with mini-album K and lead track “Algorithm.” ARTMS will truly debut as a whole in 2024. To learn how old the Odd Eye Circle (OEC) and broader ARTMS members are as a whole, here is the current age and birthday for JinSoul, Haseul, Kim Lip, Heejin, and Choerry.

How Old ARTMS & Odd Eye Circle Members Are: Age & Birthday for JinSoul, Haseul, Kim Lip, Heejin, & Choerry

• JinSoul is 27 years old and was born on June 13, 1997. (Odd Eye Circle)
• Haseul is 26 years old and was born on August 18, 1997.
• Kim Lip is 25 years old and was born on February 10, 1999. (Odd Eye Circle)
• Heejin is 23 years old and was born on October 19, 2000.
• Choerry is 23 years old and was born on June 4, 2001. (Odd Eye Circle)

Prior to the ARTMS name being established, Modhaus originally announced it had signed exclusive contracts with JinSoul, Kim Lip, Heejin, and Choerry on March 17, 2023. At that time, JinSoul was 25, Kim Lip was 24, Heejin was 22, and Choerry was 21. Haseul joined ARTMS at Modhaus on June 21, 2023, when she was 25. At the time Odd Eye Circle redebuted at Modhaus in July 2023, JinSoul was 26, Kim Lip was 24, and Choerry was 22. At the time Heejin redebuted in October 2023, she was newly 23. And if you want to go even further back, to the time that Odd Eye Circle originally debuted as a Loona subunit on September 21, 2017, JinSoul was 20, Kim Lip was 18, and Choerry was 16 then.

Choerry is the maknae (“youngest member”) of Odd Eye Circle. And while JinSoul is the oldest member of the group, Kim Lip is actually the leader of Odd Eye Circle. The ARTMS project itself does not appear to have a leader, but Haseul was typically viewed as the leader of Loona.
