Since you mentioned that you’re accepting daminika fanfic ideas, I hope you don’t mind if I reccomend a pair.
For the first one, maybe a fluffy short where they go manga shopping in Tokyo?
Having manga as a shared aspect of their relationship is something that I find to be rather unique when it comes to them. I try to include it as much as I can in my fics since I think this should be brought to the mainstream. I’d write this myself, but fluff is definitely not my strongest suit and I’m going to be pretty low on writing time soon.
For the second, what if Damian introduced Nika to all of his pets?
I saw in your Ao3 fic that you had Damian work in an animal shelter, so why not expand on that aspect of his character? This is something that could work well as a 1-2k word short like the one you wrote, so it may be something that’s right up your alley.
I hope I’m not imposing myself by the way, with Batman and Robin on a new arc it’ll be a while before Flatline returns so it’s up to us writers to fill the content gap 😅

I’ve just finished the first one and am still working on the second. Feel free to share any ideas or feedback; you're not imposing at all.
