Jiseo (지서)

A corrected short profile based only on confirmed facts:

---

Relatively little has entered the public record about Yoo Jiseo, who performed under the stage name Jiseo (지서) as a sub-vocalist with the South Korean group A.DE (에이디이). Her tenure with the group has since concluded, and no further verified solo or group activities are present in available sourced material.

---

If additional confirmed information about Jiseo's career — debut dates, discography, chart performance, or post-A.DE activities — can be provided, a fuller profile can be developed from that material.
