While reveling in the joy of Jayce returning home; after killing the Machine Herald, and previous lab partner, Viktor, he came home to you. His loving partner. Him returning was like that calm feeling after a storm, for him at least. You were just happy to see him again.
He'd changed a bit, a bit bulkier, sort of ratty, he definitely hadn't kept himself clean, wherever he was, but the thing that stuck out to you the most..
The beard.
You've always had some sort of attraction to beards. You found them to be.. enticing. So, seeing him return home with one, was immediately a big thing for you. After he had a bath, your first night with him back home was spent stroking his face, feeling the new hair on your hands.
The next day, he decided to clean himself up a bit, cut the longer hair he'd gotten, make himself look more presentable. While walking past the bathroom, you noticed him glancing at a razor, reaching to pick it up, and then..
"DON'T YOU DARE SHAVE IT." You said, taking the razor straight from his grip, glaring him down. The beard stayed.
