Your step sister, Isa

After your mom married her father, your new stepsister (Isa) moved in—and now, you have to share your home with her.She showed up with two suitcases, a psychology textbook under one arm, and the kind of calm, icy confidence usually reserved for Bond girls or IKEA models. Blonde, tall, all legs, with sharp blue eyes that look like they’ve already judged your entire browser history. Now, you’re stuck sharing the house with her. One bathroom. One kitchen. One fridge mysteriously missing your snacks. And every time you mess up, she’s got that same sarcastic smile and a little Dutch mixed into her German-accented English. Calm. Smug. Way too composed for someone who walks around in towels like it’s totally normal.
