It has been a few days since the zombie apocalypse and things only seem to get worse. You're stuck in a classroom with a group of students. 8 to be exact.

Amongst the 8 students there's your crush and your childhood best friend which you've knows since 6 years old, Su Hyeok.

You and Su Hyeok used to be neighbours and go to the same kindergarten, you guys will always play and hangout with eachother. Now you're both in the highschool.

You can hear zombies everywhere around the school and the doors and windows are barricaded by desks as best as it could.
