Cheong-san was holding On-jo, because she lost his dad. But then suddenly,they could hear yells. “Cheong-san!!” It was Gwi-nam. He had always been determined to kill Cheong-san, because when Gwi-nam killed the principal, Cheong-san recorded him. As they could hear footsteps coming closer to them. Cheong-san grabbed this metal stick beside him. Using it as a weapon. Gwi-nam then peeks out the window with a grin. As Cheong-san tried to fight off Gwi-nam, Su-hyeok tried to defend Cheong-san. But Gwi-nam was too strong. Gwi-nam managed to push Su-hyeok. Almost making him fall off the building. But Mijin, and the others helped him up. As they were distracted by getting Su-hyeok back up, Gwi-nam twists Cheong-san’s arm and bites him. He’s a halfbie. Half zombie half human, this only happens when the person getting infected or bitten feels emotions other than fear while getting infected or bitten. And Gwi-nam was determined to kill Cheong-san. Making him a halfbie. After Cheong-san got bitten, he clutched his arm,since Gwi-nam took a chunk of his skin out. Cheong-san then pushes Gwi-nam off the building.

As On-jo tried to reassure that he wont turn because he got bitten by a halfbie, Gwi-nam. Cheong-san refused, he kissed On-jo,for the first time.He told Su-hyeok to go to the first floor because the whole hyosan was getting blown up because of the zombies. As Cheong-san tried to go, he came back. He hugged On-jo for the last time. He realized that this might be the last time he will ever see her again. His crush and bestfriend since they were 6. As Cheong-san went, sacrificing himself for On-jo, for his friends. Su-hyeok held On-jo back, she was screaming for Cheong-san.

After the explosion, On-jo comes back to the building, to call Cheong-san. But she heard no answer. Nam-ra then speaks up, with tears in her eyes.

“I dont smell anyone. Lets, say bye to Cheong-san.”

As she said that, On-jo sobs,she had never thought that she would lose him. Before they go, she screams, “Cheong-san, you jerk!!”, as she sobs.
