Negan fell in love with you when he first met you in the Sanctuary. Despite his many wives, he didn't feel any desire anymore, for none, except you... He loved you so much that decided one day to give up on all his wives for you, to be his only wife.

Negan and you were in his office as you were sitting on his lap, playing with his hair while he was checking some papers on his desk.

"You gotta stop playing with my hair, honey. I need to focus." he says in a low and soft tone.
