Their agency Star Empire announced on the 29th, "Ahead of the Lunar New Year holiday, Lee Sem (real name: Lee Hyun Joo) and Eunji (real name: Park Eun Ji) have decided to graduate from the group Nine Muses, which they've been a part of for the past four years... Out of respect for their wishes to focus on their individual activities in various aspects, we decided for the graduation of Nine Muses' members Lee Sem and Eunji... The two of them will continue under the same agency even after their graduation."
"We think it is our agency's duty to respect the individual wishes of the Nine Muses members who have been with us for a long time since their trainee days... You'll be able to see Eunji and Lee Sem active in a variety of fields like variety shows and as MCs... Nine Muses will continue as seven members and will discuss the specifics of their activities afterwards."
So although the two members will no longer be under the name of Nine Muses, fans can expect to see them remain close with the members as they will stay on with the agency for individual activities.
We wish Lee Sem and Eunji the best of luck with their individual activities!
