Signature

Son Hye-ju (Korean: 손혜주; born November 13, 2001), known mononymously as Hyeju and formerly as Olivia Hye (Korean: 올리비아 혜), is a South Korean singer. She debuted as the twelfth and final member of the South Korean girl group Loona and later as a member of its sub-unit Loona yyxy. She was also a member of the k-pop girl group Loossemble.

Early life

[edit]

Son Hye-ju was born on November 13, 2001, in Sillim-dong, Seoul, South Korea,[1] and from a young age aspired to become a singer.[2] After attending Chungshin Girls' High School alongside another LOONA member Choerry, she left to train at the FNC Academy before joining Blockberry Creative.[citation needed]

Career

[edit]
[edit]

Hyeju was selected as the twelfth and final member of Loona in early 2018 after a remarkably short training period of just one day at Blockberry Creative.[3][unreliable source?] She was revealed under the stage name Olivia Hye on March 17[4] and released her self-titled debut solo single album on March 30 with the main track "Egoist".[5]

On May 30 at that same year, she was introduced as a member of Loona's third sub-unit, Loona yyxy, which released the EP Beauty & the Beat and its title track "love4eva" featuring Grimes.[6] She made her official debut with the full Loona group on August 20, 2018, with the EP [+ +] and the title track "Hi High".[7]

On March 1, 2022, Hyeju released a remake of the song "I'll Be Your Spring (봄이 되어줄게)" by Airman and Godak.[8]

On November 28, JTBC Entertainment News reported that nine members of Loona, including Hyeju, had filed an application for a provisional injunction to suspend their exclusive contract with Blockberry Creative, following member Chuu's expulsion three days earlier.[9] On June 16, the Seoul High Court ruled in Hyeju's favor, suspending her contract with Blockberry Creative.[10]

2023–present: CTDENM and debut with Loossemble

[edit]

On July 5, 2023, Hyeju signed an exclusive contract with CTDENM. The agency announced she would promote under her birth name, Hyeju, moving forward.[11] On August 2, she was revealed as a member of Loossemble along with Loona members Hyunjin, Yeojin, Vivi, and Go Won.[12] Loossemble debuted on September 15 with their self-titled EP.[13] On November 29, 2024, CTDENM announced that the Loossemble members' exclusive contracts with the label had ended.[14]

On April 17, 2025, the Seoul Northern District Court officially terminated Hyeju's exclusive contract with Blockberry Creative.[15]

Personal life

[edit]

On December 4, 2024, Hyeju attended a protest rally at the National Assembly demanding the impeachment of President Yoon Suk Yeol.[16] She expressed her solidarity, stating, "Some people might feel uncomfortable that I'm voicing my opinion about this, but I am a citizen of this country before I am an idol, so I think this is the right thing to do. Let's be strong!"[17]
