How about Silver x reader tending to each other? Maybe reader making small repairs or improvements to his cyborg parts.
I’ll see what I got! ;)
After being in relationship with him long he trust you enough on repairing his cyborg parts.
You were extra careful with them even more on his cyborg eye.
But if you make a tiny mistake he will reassure you it’s alright and fix it honestly correctly.
As you are helping repairing he teaches you some tricks you haven’t learned in engineering schools.
And if his sword or his pistol is either jammed or damaged he’ll show you how to replace them.
Soon you gotten used how how cyborg parts works, giving his life a bit easier.
