Joy, born Park Sooyoung, is a South Korean singer and actress, and a member of the SM Entertainment girl group Red Velvet, which debuted in 2014. Within Red Velvet she is a vocalist and one of the group's most active members in acting and variety, having appeared in dramas and as a regular on television programs. She made her solo debut on May 31, 2021 with the special album Hello, a collection of remakes of popular Korean ballads and pop songs from the 1990s and 2000s rather than original material, led by a modern rock reworking of Park Hyekyung's "Hello." The pre-release "Je T'aime" preceded the album. She was the second Red Velvet member to release a solo project in 2021, following Wendy. Joy's solo and acting work sits alongside her continued activity with Red Velvet, one of the leading girl groups of K-pop's third generation.
