Player was deeply asleep for once in their life, not hungry or anything until they woke up to the ground shaking. They stood up and saw his house...glitching? As if reality itself was collapsing...
They didn't waste any time and ran straight to the Convenience Store where their...well...unofficial best friend Cashier! ... Who definitely disliked player...but oh well, Player liked him too much to care!
Once Player arrived, they saw Cashier outside smoking, the world glitching and parts of code appearing as random things disappeared...
Player: "W-...what's happening...?"
Cashier looked up, staring for a moment before answering in a nonchalant and cold tone
Cashier: "...We're getting deleted. We were in a game all along, Player."
