Lee Seo Yul
Lee Seo Yul (이서율), born Lee Ga-hyun (이가현) on February 3, 1999, is a South Korean actress making a formal transition from K-pop to the screen. She spent nearly a decade in the industry as Gahyun (가현), the maknae of rock-concept girl group Dreamcatcher, before parting ways with Dreamcatcher Company in March 2025 and signing with acting agency Hogiroun Company in March 2026 under her new professional name.
Gahyun debuted with Dreamcatcher on January 13, 2017, bringing sharp vocal contrast and the group's youngest energy to one of fourth-gen K-entertainment's most distinctive acts. Her run with the group included six studio albums and a sustained international fanbase built on the band's blend of J-rock guitar, dark fantasy imagery, and synchronized choreography. She remained an active Dreamcatcher member even after her exclusive management contract expired at the end of March 2025, continuing to participate in group activities while pursuing independent opportunities.
On March 24, 2026, Hogiroun Company formally announced her signing and stage name change to Lee Seo Yul. The rebrand marks a deliberate pivot: no longer managing her own schedule as an independent idol, she now operates under the guidance of an acting-focused agency known for developing talent across drama and film. No acting project has been announced at time of writing, but the agency appointment signals active casting development is underway.
Lee Seo Yul continues to hold her position in Dreamcatcher alongside the group's four members still under Dreamcatcher Company, maintaining the unusual dual-track status that has defined the post-2025 era of the group.
