Seo Ji Soo

She debuted as a member of Lovelyz on November 12, 2014 with the group's first album Girls' Invasion. However, Jisoo did not partake in the album's promotions due to a weakened psychological state caused by false allegations made about her past. On November 16, 2021, Lovelyz went on indefinite hiatus after the members' contracts expired.

She decided to not renew her contract with Woollim. On January 4, 2022, it was announced that she has signed an exclusive contract with MYSTIC STORY to promote as an actress.
