My Stepmom's Daughter Is My Ex

High school was supposed to be my fresh start-a chance to leave behind the mess of my middle school relationship. But life had other plans. My ex is not only at the same school; she’s now my stepsister. My sanctuary has turned into a nightmare. She’s everywhere-in my home, my classes, my life. No escape. And she has the nerve to call herself the "older sibling." As if! I won’t let her win. I’m the older brother here, and that’s final. Sure, we’re family now, but that doesn’t change anything. We saw each other’s true selves back then and realized we were never meant to be. So even if we play nice for our parents, things between us will never go back to how they were.
