What Starship Entertainment Said?
Starship released separate statements for each member, and both carried a similar message: appreciation for the time spent together and warm wishes for what’s ahead. The agency thanked Eunseo for her long run with the company and expressed hope that she finds happiness in this next phase of her career, per Soompi.

SeolA received a nearly identical farewell, with the agency reflecting on shared memories and offering the same well-wishes as she moves on to new opportunities. Neither statement mentioned a specific reason for the departures, which is fairly standard practice when K-pop contracts naturally run their course.
What This Means for WJSN?
WJSN has weathered several member changes over the years, and this latest shift continues that pattern. With Eunseo and SeolA now independent of Starship, fans are left wondering whether the group will continue promoting in its current form, or whether these exits signal a broader restructuring down the line. As of now, no official statement has addressed the group’s future lineup.
