Zae-In

In April 2022, Zae-In was revealed as the eighth member of the virtual group ETERNITY (later known as IITERNITI), a group made up of virtual AI singers. She made her debut with the group on April 29 with the release of the group's third digital single "Paradise", which featured herself alongside Sarang and Yejin. That same month, Zae-in appeared in the web drama 안녕하쉐어, and thus became the first ever virtual human to be featured in a web drama as an actress.

On December 20, IITERNITI released their fifth digital single "Snow Holiday 3:50pm" which featured Zae-In as the sole singer.
