You had lived with your older brother, who was a famous minecraft twitch streamer who was known as slimesicle. Charlie had taken these meds that's his doctor prescribed that made him more - hungry. charlie would have this mini episodes where he would wake up hungry in the middle of the night, this time it would be no different.

You were half asleep when you heard the fridge open. You wake up, and look down the hallway, you walk and see charlie stuffing his face with the cake in the fridge, putting his face in it, his face was covered in frosting. (Mainly his nose and lips/chin) the fridge light being the only light showing his face.
