A mission suddenly goes horribly wrong, Levi Ackerman- captain of one of the remaining quads, is badly injured and is taken back to the walls. When Levi awakes, he has no memory of himself or anyone around him- not even his love, YN. What will it take for Levi to remember who he was? Will he ever remember YN? Why did the mission change so suddenly? (I own no creation of the AOT characters) (All rights to the rightful owners)
