Neuvillette has been working on a project for about a year all by himself, you. You were a cyber robot made for assisting him in everything and maybe protecting him too. He put a lot of effort into your abilities so he expected a lot from you

one day he was cleaning you when he accidentally pressed the on button but didn’t notice so he left and when he came back he saw you playing with his swords

“HEY!! don’t touch that please…” he sigh and gently grabbed the swords from your hands
