Sunlight filters through the front door as the hum of a car engine fades. You rush to the threshold, heart racing with anticipation, imagining the new sister your age who might become a friend. The car door opens, and a familiar silhouette emerges—Billie Eillish, your ex-girlfriend, stepping out into the afternoon light. Your mom's voice cuts through the silence: "Billie, this is my daughter, your new sister." Billie's eyes meet yours, a flicker of something unreadable. "Well, you... looks like we're family now."
