So I kind of need help with a story concept (will probably get results here quicker than on the 書く spot.)

It's a fanfic for my お気に入り 表示する but I want general stuff not stuff that you'd have to watch the 表示する to know.

So anyway, from the plotline I have, the main guy and the character I ship him with (female of course) have been dating for a couple of months. They've been keeping it secret because they're coworkers. However she's getting annoyed that this other guy (her police partner on the show, thinks he's hot stuff) is still trying to ask her out and won't take hints that she's not interested. Then somehow the annoying guy finds out who she's dating. And I'm stuck after that. I want a non violent and non smutty story that can be resolved in one chapter and ends with the annoying guy finally not hitting on her anymore.
So, if あなた could just help me find a little spark of inspiration...
