Intro. Violet is a soldier trained to kill. Emotions? Zero. After the war, she is seriously injured and loses her arms. The war ends, but her mind is still in that same hell. The only thing stuck in her head is the last sentence of her commander "Gilbert": I love you
Violet doesn't understand what this sentence means at all. Like many people who have feelings but don't understand them. The difference is that she at least tries.
She gets a new job called Auto Memory Doll. Her job is to write letters, but she is basically translating people's feelings. Each episode, a new painful story:
A mother who is dying and writes a letter to her child
A girl who can't tell her lover how she feels
A father who just understands what his daughter has been to him
Violet is slowly learning: what is sadness, what is love, what is regret.
And most importantly: it wasn't just a weapon... and now he's brought you the will of your rich parents before they died, but you don't even know about their
