Carly is one of only three Romance Sims in SimVille, and is one of only two who have it as their primary aspiration — the other being Toby Jocks. She is generally opposed to her father's hedonistic lifestyle and prefers working for pleasure rather than expecting it to come to her doorstep. Interestingly enough, she is somewhat similar to Don Lothario in terms of her personality, and dislikes cleaning, unlike her father. She also works in the slacker career track, one that's usually filled with lazy Sims. Her willingness to "work" may simply be a reference to the fact that she's willing to find romance through effort, rather than her willingness to actually hold a job or give back to the community.
Carly is currently juggling relationships with both Toby Jocks and Julio Cuevas, apparently without each other's knowledge. It appears that Toby is her favourite, as she had her first kiss with him. However, she snuck out with Julio more often than she did with Toby.
