Aftermath () is a 2014 South Korean web series starring Kim Dong-jun and based on Kim Sun-kwon's webtoon of the same title.
After a car accident, high school student Dae-yong starts seeing people's eyes turn either red or blue. Soon he realizes there is a pattern and that red eyes mean that person is going to die and blue eyes mean that person is going to kill someone, and that he is now capable of saving people. Not only good things come out of that, as there is a cafe owner with the same ability as him but is obsessed with murdering people. Meanwhile, his relationships with his girlfriend, Hee-kyung, and best friend, In-ho, are at risk due to him having changed so much after becoming known as a hero.
