Lee Seo Yul
Lee Seo Yul (이서율), born Lee Ga-hyun (이가현), is building an acting lane on top of the global audience she first earned as Gahyun of Dreamcatcher. That history matters. Few idol-to-actor pivots arrive with this much stage mileage, camera fluency, and international fandom already in place. After debuting with Dreamcatcher in 2017, she spent years inside one of K-pop's most concept-driven groups, helping the act turn dark-rock storytelling into a durable brand with worldwide touring power. In March 2026 she signed with Hogiroun Company and began using Lee Seo Yul for screen work, signaling a serious move into acting rather than a one-off side project. Her current positioning is clear: retain the recognition she built in Dreamcatcher while opening a longer-term film and drama path. For HITKULTR, that makes her one of the more watchable 2026 transitions because the appeal is not novelty. It is the combination of idol discipline, established fan reach, and a new performance chapter with room to grow.

Fans Also Ask
Who is Lee Seo Yul?
Lee Seo Yul is the acting name of Lee Ga-hyun, better known to K-pop fans as Gahyun from Dreamcatcher. Born on February 3, 1999, she debuted with Dreamcatcher in January 2017 and signed with Hogiroun Company on March 24, 2026 to begin a formal acting chapter while still remaining part of the group.
Was Lee Seo Yul in Dreamcatcher?
Yes. Before adopting the name Lee Seo Yul for acting, she spent years promoting as Gahyun in Dreamcatcher. She debuted as the group's youngest member and worked as lead vocalist and lead rapper across the act's core album cycle. Even after leaving Dreamcatcher Company in March 2025, she continued to remain active as a Dreamcatcher member.
When did Gahyun change her name to Lee Seo Yul?
She adopted Lee Seo Yul as her professional acting name in March 2026, when Hogiroun Company announced her exclusive contract. The move created a clearer separation between her idol branding and her screen career, which is a familiar strategy in Korea when an artist wants casting directors and the public to read a new lane more seriously.
Which agency represents Lee Seo Yul?
Lee Seo Yul is represented by Hogiroun Company, a Seoul-based acting agency that announced her signing on March 24, 2026. The agency positioned her as a rising actress rather than simply an idol crossing over, which is an important distinction for how her next projects are likely to be pitched and cast.
What is Lee Seo Yul known for right now?
Right now she is best known for her Dreamcatcher history and for the name-change announcement that marked her acting launch. That update put fresh attention on her earlier performance experience, public profile, and long-term visual identity inside the group, all of which now feed directly into the way her acting career is being framed.
