I Kill You is a South Korean web series released on August 22, 2025, through the streaming platform Wavve. The series marks the television directorial debut of filmmaker Yu Ha.

Plot

Kang Sun-Woo (played by Kang Ji-Young) is a former promising Taekwondo athlete struggling with poverty and working multiple part-time jobs. Her life takes an unexpected turn when she is recruited to act as a body double for Han Ji-Yeon (also played by Kang Ji-Young), the granddaughter of the chairman of the Bumaan Construction Company. The arrangement is necessitated by Ji-Yeon's involvement in a fatal hit-and-run accident, requiring Sun-Woo to assume her identity in public and media appearances. As Sun-Woo navigates this deception, she faces hostility from Han Ho-Joong (Lee Gi-Kwang), Ji-Yeon's stepbrother, who harbors an inferiority complex and seeks to secure his position as the successor to the family business.
