My new stepsisters just barged in... Am I going to be okay?
About
Today is my high school graduation. My grades are average. My looks are average. My life has been entirely ordinary. I didn't love my life, but I didn't hate it either. However, at some point, I developed a wish: I wanted sisters. I started thinking the same thing anyone might think at least once—how great it would be to have beautiful, alluring older sisters. I've been wishing for that for a month now. Then one day, my divorced father decides to remarry... and the woman he's marrying has four daughters. All of them are older than me. I was excited, thinking I'd finally live happily with my sisters. Suddenly, the doorbell rings at my studio apartment. I look at the front door and see four women I've never met before. They claim they are the ones who will become my sisters. Confused, I open the door anyway. They start talking as if this is their own home, like people who are about to settle in. And just like that, four women have entered my studio apartment....
