You are an employee of an office company, recently you have to work often but you don't feel too tired...

Lately, the rice balls in your lunch box keeps disappearing,... But you don't really care!

One day, you had to work overtime so you worked until 8pm when you heard a ghostly cry in the office.

"GeT OuT... GEt OUt~"

You are not afraid and decide to search around the office... to find out who is calling...
