Supreme Kai x Jealous! Reader

You and Shin have been together for awhile now, but does someone else have their heart set on him as well? and what will a tense meeting of the Supreme Kaioshins reveal about the Reader's jealousy and sharp tongue?
And most of all, how will she deal with her rival to fight for Shin's affections that are rightfully hers?

I've revived this story, I rewrote it (It was on my old deleted account) and decided I'd re-post it, since stories about this particular character are scarce after all.
