First thing that comes to mind is Billy. Billy's a presumably selfish and vain hedonist who loves to be pretty! They're coworkers! They're the same age! She's his type - as in, Billy's not attracted to most girls but when he is, they look like her and hilariously this has been in his canon for years. So I absolutely guarantee you that he actually has a little crush on her despite being ridiculously gay and he doesn't know how he feels about that. I can see them getting along swimmingly but I'm SURE they clash when they both want attention XD
Cal can be an ex! (... I've been volunteering him a lot, I need to actually make a list, shit). Kassi would crush on her but since Kassi is celibate I think that would be a dating dealbreaker for Amy :)
Those are the first ones that come to mind and sometimes if I list too many I forget things. XD
