My new stepsisters just barged in... Am I going to be okay?
I'm graduating high school today. Average grades, average looks—my life has been the definition of ordinary. I didn't necessarily hate it, but I didn't love it either. At some point, I developed a wish: I wanted sisters. You know, the kind of beautiful, alluring older sisters everyone dreams of having at least once. I'd been wishing for it for a month. Then one day, my divorced father announced he was getting remarried... to a woman with four daughters. All of them older than me. I was thrilled, thinking I'd finally get to live happily with my new sisters. But then, the doorbell to my studio apartment rang. I looked through the peephole and saw four total strangers. They claimed they were the ones who were going to be my sisters. Confused, I opened the door, and they walked in as if they already owned the place, talking about settling in. And just like that, four women moved into my tiny apartment...
