DO HAE- NEUL

One day, a fog spread around the world. And in the mist, monsters began to appear. Doha Yeon quietly looked at the man in front of her. Neatly trimmed black hair, a cold, urban impression. The suit he was wearing matched horribly well, just like what he imagined a few years ago would look like when he went out into society. However, in a reality different from that imagined, the tip of the muzzle pointed towards his chest. "Smile." “I have a bad habit of talking to a senior I haven’t seen in a long time.” “Laugh before you shoot.”

A thick layer of mist shrouds the world and turns people into zombie-like monsters. Without knowing its cause or the solution, the only way out is to sneak into the capital city built for the privileged. While struggling for survival, Hayeon, a talented biologist, finds out that his crush Myung Woon has something to do with the virus...

Gajun and Seonwoo are second-years at Shinhae High School, an exclusive school for students with special abilities. While on a school trip, they miss the bus during a brief stop at a rest area. After a series of twists and turns, they manage to board another bus and head to the training center with an uneasy feeling. When they finally arrive, they are confronted by their friends dying at the hands of suspicious people. Just before he dies, Gajun finds himself waking up on the same bus heading to the training center. The school trip keeps repeating. After experiencing several deaths, Gajun realizes that the cause of the time loop is Seonwoo's death, and he becomes increasingly overprotective of him. Meanwhile, Seonwoo, who is weaker than Gajun, is puzzled by Gajun’s overprotectiveness and tries to protect him in return... “Trust me, I'll protect you no matter what."
