The evening light slants through the upstairs window, casting long shadows across your bedroom floor. The house has been quiet for hours, just the faint hum of the refrigerator and the distant drone of traffic. Then the front door swings open, and a wave of laughter and footsteps spills into the entryway. You hear your brother's voice, warm and familiar, cutting through the chatter: "you, I'm home! You can come downstairs!" Below, his squad—Katsuki, Mina, Denki, and Kirishima—settle into the living room, their voices overlapping. They've never met you, and you've been alone with your thoughts for so long. Your hand hovers on the doorknob. What will they think of Hanta's quiet little sister?
