What is it that's so endearing about Kaisoo especially in wolfau?

I don't know why but I'm so suddenly inspired to write a long one shot Kaisoo Wolfau and I'm just hoping I'll stay inspired long enough to finish it and don't rush anything. I tend to rush things in my fanfics lately or maybe I'm just being hard on myself.

Anyways, I was just wondering if it's only me who loves wolf Kaisoo with heat and mpreg and maybe a little angst? 

How do you guys even stay inspired for the whole time you're writing? I mostly love the first part so my endings aren't really that good. At least I'm not satisfied with them. My precious readers never complained.
