Seo Su-bin () is a South Korean actress. She is known for her breakout, debut lead role in The World of Love for which she won the Best Actress Award at the 2025 Red Sea International Film Festival.
Early life Seo was born in Ulsan, South Korea. She danced as a child and even briefly underwent K-pop idol training.
Seo studied at Pyeongtaek University under the Department of Theater and Film, focusing on practical skills and artistic sensibility by actively participating in various performances, video productions, and field-oriented projects during her studies.
Career Prior to The World of Love, Seo never acted. A fan of director Yoon Ga-eun, she was cast "after three meetings and an acting workshop", much of which felt like a "blind date". Yoon was charmed by her eyes, her honesty in-person, and her immediate synergy with other actors, on top of her taekwondo experience, which was crucial to Yoon's script.
On the festival circuit, Seo drew acclaim from Korean and international critics alike for her performance. At the Red Sea International Film Festival, she won the Best Actress Award by a unanimous decision from the jury.
