My "Bachelorette" Challenge

So a while back, I posted a poll about how my sim had gotten into a love triangle with the Pleasant twins and asking what I should do about that. Ultimately, with some feedback, I decided to have my sim go for the serial romantic aspiration to get the player reward trait (and, y'know, see if all blows up in their face along the way lol.) Well, they've completed the aspiration...and now I'm thinking of doing some kind of "bachelorette" with the 8 girlfriends, eliminating them one by one till we have a winner and then getting married or something. I don't really have a clear plan yet, so if anyone has any idea/suggestions on how to go about it, I'd love to hear it! I've moved the girlfriends in together, but haven't done much else yet. I'm considering having one day where I play my sim, and then one day where I play the girlfriend's household, and then have some kind of elimination ceremony based on...something. Thoughts?

Btw, here are our eight romantic finalists

And this is my sim

She's a good, creative, perfectionist mermaid, and she's already completed the Joke Star aspiration as well as Serial Romantic, is a 2-star celebrity and is at the top of the comedian career--so a pretty good "catch" I'd say! :D
