I have ideas for 2 future fanfictions (both of them will be Natasha Romanoff x Reader)
First idea/fanfiction: Y/n is a mermaid that finds out she can become human (aka have legs) when she's out of the water (like in the shows H2O/Mako Mermaids) Y/n meets Natasha, they start spending time together and fall in love
Second idea/fanfiction: Y/n is a ghost (like in the Casper movie) Natasha and her two sons, Billy and Tommy, move into the old mansion (Y/n's house when she was alive and that Nat inherited from her biological parents) Y/n quickly becomes fond of the twins and develops feelings for Nat
Which one should I write first?
