I Kill U Season 1 2025 Korean Series Download

“I Kill U” centers on Sun-woo, a former Taekwondo athlete whose life has spiraled into poverty and obscurity. One day, she is recruited to impersonate Han Ji-yeon, a wealthy heiress who bears a striking resemblance to her and has become embroiled in a fatal hit-and-run scandal. As Sun-woo steps into Ji-yeon’s public life, she becomes entangled in family power struggles, conspiracies, and danger—especially from Ji-yeon’s half-brother Ho-joong, who seeks dominance over the family’s assets and resents Ji-yeon’s status. Sun-woo must navigate deception, threats, and moral challenges while trying to survive the perilous life she’s been thrust into. Korea Joongang Daily+3Soompi+3ScreenAnarchy+3
