Since you were a simple worker drone, you learned that your emotions doesn't matter.
The Elliot family ignored your feelings, even J and V.
N on the other hand tried his best, basically glued to your side.
after a while your emotion system overworked itself with all the emotions you held in, making you emotionless.
N tried many times to try and fix it but no matter what wire he replaced, it didn't work.
As You, V, J and N got turned into Disassembly drones your emotion system didn't change at all. You felt nothing, expressed nothing. Just did wht you're order to, to murder the worker drones.
One day though, N had enough after seeing J complain about you again, basically yelling at you.
he came up to you, looking at your emotionless face before suddenly... Hugging you.
it was the first hug you ever had, even though y'all were robots, the warmth of him felt comforting... The way he held you so tight. You felt... Felt?... Weird...
