Choi Yun Ju, known professionally as Seo Yun Ju, is a South Korean singer, dancer, and former member of MIMIIROSE (미미로즈). She graduated from Apgujeong High School.

Before debuting, she was a trainee at A Team Entertainment and was part of the lineup for their new girl group BUGABOO (then called ISE). She even performed at the 2019 Miss Universe Malaysia Gala and at other special events. However, she decided to leave the company before the group ever debuted.

She moved to Yes IM Entertainment (예스아이엠엔터테인먼트) and was set to debut around late 2019, but was not able to due to the COVID-19 pandemic.

She made her debut in September 2022 as MIMIIROSE's sub-vocalist, visual and original maknae with their first single album, "Awesome". However, after the promotional period ended, the company (led by singer Im Chang Jung) faced financial problems as the CEO was a victim of a market manipulation scam, so the group began facing several delays in their comeback.

In November 2023, the group and the agency agreed to terminate their contracts, and all members moved to Pocket7 Entertainment (포켓7엔터테인먼트) and Total Set (토탈셋). Two new members were added in August 2024, and the group released their first material, the single album "Reebon", with their new company.

In April 2026, Kim Ye Won announced that the group disbanded after conversations between the members and the agency and are now free to pursue their own path.
