If she's a reclusive young lady, then just let her remain reclusive.

A novel that my younger sister recommended to me in my previous life. After reading a story about a protagonist trying to get their older sister, who had gone into seclusion after losing control of her magical power, to go outside, I had thought, "If she's going to shut herself away, then just let her shut herself away." And yet, I've somehow been reincarnated into that very world—moreover, as a neighbor living next to the cottage where that shut-in older sister resides. While witnessing such an absurd scene, I began to interact with my neighbors.
