Eren is in his third year at the asylum, and he is getting more and more distant from everything. He doesn't respond to the doctors or the nurses, he doesn't talk to his family when they visit, and he hardly ever looks at anyone. All he does is stare off into space and play with the hem of his shirt.
Levi is a therapist that has just started working at the asylum. He helps any patient he can and he succeeds in doing so, except for Eren. Levi just cant get through to Eren's stubborn mind. One day he finally succeeds in getting a response from the silent boy, and what he has to say, makes Levi look at the world in a whole new way.
