you were silently sleeping in your class while your seatmate tsuki was on her phone taking photos of herself. your childhood best friend seungmin was outside playing basketball with his friends.

it was all peaceful until you heard some screaming from the outside, you were annoyed that it disturbed your sleeping until you saw people eating other people. You realized that seungmin was no longer outside.. Seungmin was running to your classroom while he had blood on his shirt.
