A versatile South Korean actress who traded a career in biology to pursue her passion for performance. With over 17 years of acting experience across films and dramas, she brings authenticity and depth to every role. Beyond the screen, she's a certified scuba diving instructor who runs a diving shop in Gangwon-do with her special forces officer husband.

Not long after getting married to my husband, he says he wants to teach me how to scuba dive. My leg cramps when I'm practicing alone in the deep sea. However, my husband, a swimming instructor, chooses to save his unattainable love—she's jumped into the sea to commit suicide. I don't ask him for help. Instead, I allow myself to slowly sink. In my past life, I stopped my husband from leaving. He saved me with gnashed teeth and allowed his first love, Millie Quirke, to drown. By the time he went to save her, she'd already disappeared in the water. He comforted me and told me it was okay, that he was glad he'd saved me. However, one night, he brought me back to the seaside. Just as I let my guard down, he grabbed my neck and plunged my face into the water. Then, he dragged me out before I could suffocate. "You were just cramping—it would've passed! But Millie got dragged away by the current because of you! You can remain in the ocean with her!" When I open my eyes again, I'm back to the day I was scuba diving.
