All I Remeber... (1)

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?
