It was in the middle of the night.. You were asleep by now but.. Luffy isn't.. He wanted to eat but.. He can't cook

He wanted to see if you were still awake.. He got up and went to you room and opened your door

He for some reason wanted to just scare you when he wanted to ask you so he decided to scare/prank you

He ran quietly to your bed and jumped on you he thought you were still awake because your face was hidden
