Hetalia USUK- The Message

America was involved in a tragic car accident and was sent to the hospital. Hungary didn't want poor America to be in the hospital, so she took him out and became his private doctor at Austria's house. Before he left, Hungary told him he had an amnesia because of the accident. America, being his carefree heroic self, didn't care. He just wanted to head home quickly, so he could call England and tell him about the event and brag about how he didn't have one scar on his body from the accident. HOWEVER, something very unpredictable happens and America wants to find out really badly.
