I've an idea I could use help with, a woman manipulating three guys.

I've made the household and have played them a bit so far. 

She did end up with self absorbed, materialistic and commitment issues. 

One guy is a geek, genius and lactose intolerant. Very much looks like the awkward boring nerd, he's the guy she exploits for his smarts. Currently has a tech job but he dreams big, wants to be an engineer later, when there's funds and a place at home to work on robotics. 

Another is a gullible good guy. Idealist, generous and heart on his sleeve. Guy wants a family and probably believes whatever lies she tells him without question. She exploits him for being a care taker. He does most of the cooking, gardening and such. And also works as a salary person to further show what a doormat he is. He looks like an average clean cut guy. 

And the third guy is adventurous, ambitious and a perfectionist. He's hot and all muscular, feels pretty confident she'll pick him over the other two. Has no idea she has no intention to picking any one of them. He went in the army and is her main money maker, also eye candy. The one she'd be most likely to sleep with.

He's received several promotions already so has been the only one to be flirted with so far, though the other two did get a compliment for their one promotion so far. 

It's quite fun to play, she has her own bedroom with a decent double bed and some furniture, the guys share a bedroom with the cheapest beds. And anything she benefits from or has the want to spend money on, is the priority to buy first. In everything she's the first priority. One meal serving left? That's for her. More than one sim needs to use the toilet or shower? she goes first. 

She does not work either, she does go around collecting stuff in the region. And practising her magic when all the men are out of the house. I play her magic as a secret they don't know about. Gives her a way to fix broken things and clean too when they aren't around, since she's not going to ever do that by hand. she has three men for that. 

Don't forget the Serial Romantic aspiration so she can get the Player trait where no one will get jealous. Just for ease of gameplay

Maybe you've made them already, but I wanted to weigh in! She should definitely have the materialistic trait as well, right?

A "type of guy" might be the heroic sort who thinks this is a situation he can win. Active, Romantic, Ambitious?

& of course one of the guys ought to have the Geek trait for the rare collectible odds.
