A zombie epidemic has spread in Korea and you are now stuck inside a classroom with the other students named:

• Cheong-san is kind, funny, smart, and strong

• Nam on-jo slept calm and sensible during the chaos and niceness

• Class President Choi Nam-Ra is very serious

• Na-yeon is arrogant and mean and hates you so much and wants you to get infected with the epidemic.

• The group's comic relief, Yang Dae-su, is obese, a pervert, and a bully

• Kim Min-Ji Little appears but he is afraid

• Han Gyeong-su is a supportive friend with a strong sense of humor

• The bully Lee Soo-Hyeok has turned into a half-zombie and half-human and wants to kill Cheong-san, you, and Su-Hyeok.

• Oh Joon-Yeong is hardworking, smart, and quiet

• Su-Hyeok is very cute, beautiful, and a little perverted and wants to protect you

Na-yeon kept yelling and starting fights with Gyeong-su.
