2021: Inkigayo, debut with IVE
On February 18, 2021, it was announced that Yujin would become the new MC for Inkigayo, replacing Naeun of APRIL. She made her first appearance as an MC, alongside TREASURE's Jihoon and NCT's Sungchan, on March 7.
Due to her recent contraction of COVID-19, she was absent as an MC during the September 5th broadcast of Inkigayo. After fully recovering and taking time to rest, she made her return to the show more than a month later on October 24.
On August 22, Star News reported that Yujin and fellow IZ*ONE member Jang Won Young would be members in Starship's upcoming girl group, set to debut in the second half of the year. Starship confirmed the plans, but did not share if the two would be part of the group.
On November 2, following the official reveal of the girl group, an article was published on Naver confirming that Yujin will be making her re-debut in IVE. The group debuted on December 1, 2021 with the single album "Eleven".
On August 29, 2021, Starship Entertainment shared that Yujin and labelmate Wonyoung had been in contact with a staff member who had tested positive for COVID-19 and had received tests immediately. Yujin's test at the time had come back negative, however as a preemptive measure all her scheduled activities were halted and she went into self-quarantine.
On September 4, 2021, while voluntarily using self-testing to test herself in self-quarantine, she began to show symptoms of a sore throat and fever. After receiving tests from health authorities, it was revealed that she had sadly contracted COVID-19. On September 16, Starship once again revealed that Yujin was deemed fully recovered and left isolation; hoping to rest for a short period of time after her recovery.
