Canon
Cheong-san and Su-hyeok are the male leads of the show. Prior to the apocalypse, Cheong-san and Su-hyeok were good friends. They were both in the same class in Hyosan High School and they were both good at fighting. The history behind their friendship is largely unknown. Cheong-san was romantically interested in Nam On-jo, another close friend of his. When the apocalypse began, both Cheong-san and Su-hyeok made it back to their class, where they met with other surviving students and formed a survival group. However, their PE teacher, Kang Jin-gu, entered the classroom despite being bitten, and infected one of the survivors, Kim Min-ji, forcing Cheong-san, Su-hyeok and the other survivors to flee to the science lab. They then left the lab and met up with their teacher, Park Sun-hwa, in the broadcasting room. While the group was hiding in the broadcasting room, both Cheong-san and Su-hyeok entered the teacher's office by climbing down the windows in order to search for a working phone in order to call for help. However, they encountered fellow student Min Eun-ji smashing all the phones. She began to attack Cheong-san after she noticed him, and Su-hyeok helped to defend him. However, she began screaming, drawing the attention of zombies, resulting in the separation of Cheong-san and Su-hyeok, with the latter managing to grab a working cellphone before fleeing.

The survivors, including Su-hyeok, who had managed to make his way back to the group, found Cheong-san hiding in the music room during their drone exploration. They later reunited with him. The group then went to the rooftop in order to catch the attention of rescue helicopters. However, they were unable to access the rooftop as the door to the roof had been locked by another student. Eun-ji then tripped the fire alarms, unlocking all the doors, but the helicopters had already left by then. They then decided to stay on the roof. However, just as they were about to be rescued, the rescuers were given orders to execute the group. They were spared, but left stranded on the roof.

After it began to rain, the group used the weather to escape the roof. Shortly after running away from the group, they met and grouped together with another group of survivors. The group then escaped to a construction site, where they believed they were safe. However, they were soon attacked by the school bully Yoon Gwi-nam, who had been infected. Gwi-nam then fought Cheong-san, who decided to fight the former in order to allow his friends to escape. He lost, and Gwi-nam, who ate his eye. When the military bombed the school and by extension the construction site, Choeng-san grabbed Gwi-nam and jumped down the elevator shaft, using the latter as a shield. Their fates are left ambiguous. Su-hyeok manages to escape with the remaining survivors, and returns to Hyosan after the city was deemed safe again.
