Signature

Cho Ha-seul (Korean: 조하슬; born August 18, 1997), known mononymously as Haseul (occasionally stylized as HaSeul) is a South Korean singer. She is the leader of Loona, its sub-unit Loona 1/3, and a member of Artms.

Early life

Cho Ha-seul was born August 18, 1997, in Suncheon, Jeolla, South Korea and raised in Beolgyo. She sang in a children's choir while she was in elementary school. Haseul went to high school in the United States for one year. Instead of pursuing her original plans to study opera in college, Haseul became a Blockberry Creative trainee after she was cast at a song festival her music teacher convinced her to participate in.

Career

2016–2022: Debut with Loona and sub-unit Loona 1/3

Blockberry Creative began releasing teasers for the third member of Loona in early December 2016. Haseul was revealed as the third member on December 8. On December 15, Haseul officially debuted as a member of Loona through her eponymous single album with tracks "Let Me In" and "The Carol" featuring fellow members Heejin and Hyunjin.

In January 2017, Haseul collaborated with fellow member Yeojin for the song "My Melody" on Yeojin's debut single album. On March 13, Haseul debuted alongside members Heejin, Hyunjin, and ViVi in Loona's first sub-unit Loona 1/3 with the mini album Love & Live. Haseul officially debuted with Loona as a full group on August 20, 2018 with the release of their debut EP [+ +].

On November 28, 2022, JTBC Entertainment News reported that nine members of Loona, including Haseul, had filed an application for a provisional injunction to suspend their exclusive contract with Blockberry Creative, following member Chuu's expulsion three days earlier.

2023–present: Solo activities and re-debut with Artms

In June 2023, after her contract with Blockberry Creative was suspended, Haseul signed with the label Modhaus to join fellow Loona members Heejin, Kim Lip, Jinsoul, and Choerry in a new project, where they would eventually debut as Artms. On September 6, Modhaus announced Haseul's first small theater concert series, "Music Studio 81.8Hz", to be held from October 26 to 29 and teased the reveal of an unreleased song. On October 26, she released the teased solo song "Plastic Candy" as a digital single.

On December 9, 2024, Haseul released her second digital single "Fragile Eyes".

In April 2025, Haseul's contract with Blockberry Creative was officially ruled invalid by a judge. In September, Modhaus announced Haseul's second small theater concert series, "Our Fairytale", to be held on October 25 and 26. On September 18, she released her third digital single "Love Poison".

In 2026, Haseul paused promoting with Artms to undergo surgery on her shoulder. In June, she released the single "Again" in collaboration with composer Kim Hyung-suk. On September 8, she released the single "Afterglow". A third concert series "Inner-Ego" was announced for November 7 and 8 with four concerts total. The final concert was noted for having a pay what you want pricing plan.

Personal life

Haseul took a hiatus from entertainment industry activities from January 2020 to May 2021 due to anxiety. In 2026, Haseul underwent shoulder surgery and paused entertainment activities to recover.

Haseul and her family are avid Kia Tigers fans, and Haseul has thrown the first pitch and sung the national anthem at multiple games.
