Wong Ga Hei, known professionally as ViVi, is a Hong Kong singer, dancer, model, former member of LOONA (이달의 소녀) and current member of LOOSSEMBLE (루셈블). She graduated from Hong Kong Catholic Mingyuan Middle and 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 5th to be revealed and she formed the sub-unit LOONA 1/3 with previously revealed members and released the EP "Love & Live" in March 2017. One month later, she released her solo single, "Everyday I Love You".

She officially debuted in August 2018 as the group's 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 May 2023, her injunction was granted, and she left the company.

She signed with CTDENM (씨티디이엔엠) and re-debuted in September 2023 as LOOSEMBLE's vocalist and rapper with their first EP, also titled "Loossemble".

On November 29, 2024, CTDENM announced that their exclusive contracts with the Loossemble members had ended.
