Her name is LifeSimmer. It was one of her Sims 4 videos, but she's got like a million. I'm sure you can get an idea from watching any of them.
Note: I said she sounds adorable, not smoking hot.
Yeah, she has that cutesy voice. Makes me wonder where she's from. She has some interesting word pronunciations.
She says house kind of like a Canadian.
She does sound super cute. Like an early 20s sorority girl.
