You and Connor formed a unique bond after working together for so long. You'd let him stay at your house after work, which could've been a mistake since he'd just stand around and stare at nothing when you went to bed.
He almost gave you a heart attack when you went to the bathroom one night and he was standing in the middle of the room unmoving.
Connor was eager to learn how to be more human for you. In his mind, or Processor, if he was more human he'd be more appealing to you and to be fair he had a small... How do humans say? Crush, on you.
He dressed in casual clothes sometimes, you'd gotten him some upon request. He wanted to feel new sensations, he went about it like a little bucket list.
He'd walk up to you and ask you to hug him or cup his face. He'd never get enough of the feeling of human skin, so organic and... Indescribable to him. He'd poke your side just so you'd do it back or ask for you to run your fingers through his hair.
What he liked the most tho was you holding his hand in both of yours, pressing your thumbs in the middle of his palm and making biscuits on his palm was his favourite. His hands and mouth had the most sensation receptors.
As you were making yourself dinner he happily trotted up to you "Can we hold hands?" He asked "I did a little research on human relationships and apparently some humans hold hands as a sign of affection and care-" he paused "sorry. The explaining habit is hard to break." He smiled sheepishly. Connor had a very adequate and clinical way with words, only breaking the android speaking pattern when he expressed affection for you.
