I would suggest is that you move your fanfics over to the dedicated fanworks thread. Since this is the discussion thread, your work might get drowned out, and nobody wants that. 
Also, as long as you don’t attempt to make a profit off of your stories, then there shouldn’t be an issue with the ToS.
There’s an FAQ in the second post of this thread that has compiled the most important of Sera’s answers regarding the Wayhaven Chronicles, including love triangles. It can be found under the Romance and Gender Questions section of the post.
I hope it answers your speculation!
