@Mystic-Shadows Hey!! I am sooo sorry! I didn’t realize you'd requested anything! I'll definitely write that for you in the Invincible era!
I write imagines, pretty much the same way I write my books. I pretend their relationship is already established, and I write them like a chapter in one of my books. The biggest thing is that when writing, your imagine, is that your original character doesn't need a ton of character development, meaning you can pretty much tell the story. If that makes sense! As long as your primary character is true to form, it comes together for me.
