Aria

Sometime in early 2022, Aria, under the name of Ami (아미), joined GBK Entertainment and became a trainee under their online training platform Universe, which aims to select girls to became potential members of a future girl group. On November 29, 2022, now known as Aria, was revealed as one of the five selected members of GBK's upcoming girl group MEP-C. However, in early 2023, she presumably left the group after the deletion of her profile post.

On March 7, 2023, she, along with Nova, were seen in the line-up reveal video of the 44th K-Stage Yes or No concert of which the upcoming girl group X:IN would be performing at on March 12, therefore confirming her as a member of the group. On March 8, 2023, she was officially revealed as the fifth and final member of the group. They debuted on April 11, 2023 with their first digital single "Keeping the Fire".
