Eat Melon Cubs in the Apocalypse

On an ordinary day, a sudden disaster plunges mankind into an existential crisis. The world was terribly quiet that night. As some people woke up, in the quiet floors, there were bursts of chewing sounds "Kazi, Kaz, Kaz" coming from certain rooms, and the sound of something hitting the door "Kang, Bang, Bang", but these sounds did not disturb the tranquility of the night.
