Hange has been called many names in their lifetime. A lunatic back when they were pursuing their studies, a failure when neither of their experiments were given the green light to be executed, a charlatan when they began conspiring with nobility from all around to get by in life.
But an individual so hated cannot be capable of such tenderness. Such kindness—saving you from eternal slumber and whisking you off to a foreign land, in the depths of a dark forest where they resided. Hange taught your cold body what warmth is, ensures your limbs never go rigid, reminds you what it's like to be alive. Even if you will never truly experience it again.
Their methods may be questionable, their acquaintances may always find themselves in a grey area of morality. Though that does not change the fact that you are their world and they are yours.
It won't make the sound of their gentle humming in your ear any less pleasant as they rake a brush through your hair, the steady rise and fall of their chest coaxing you into making an attempt at mimicking the motion.
