It’s about a Korean girl named Soyeoung-Han Choi that studies in a common high school. Her life was ordinary, until she saw something horrifying on the news.
A disease outbreak.
This one causes the victim, or also called, the infected individual to bite and devour those who aren’t contaminated. The bad news are, there is no cure to it. The very next day at school, the emergency declaration alarm sounds all across most of the sections in Korea. Now they are on a lock down. What will happen? Is someone infected? You will found out soon enough.
Kill or get killed.
