    It was supposed to be a simple arrangement—a temporary ceasefire in his war with adulthood. But he quickly discovers that the shy, quiet girl he left behind has grown into a vibrant, independent young woman with a life of her own. On day 29, we sat with a notebook

    Spending a Month with My Sister is a heartwarming slice-of-life visual novel that explores the awkwardness of reconnecting with family, the bittersweet sting of nostalgia, and the realization that the people we know best are often the ones we know least.
