Bye-Bye Brother

For as long as she can remember, Kotono has existed entirely within the shadow of her older brother. Her daily life and sense of self have been shaped by his overwhelming presence, leaving her accustomed to a quiet existence defined by comparison. She has spent years navigating a world where he was always the central figure, quietly accepting her secondary role in their family dynamic without any expectation of change. However, the fragile balance of her routine is abruptly shattered when her brother unexpectedly returns home after spending many years living abroad. His prolonged absence had finally allowed Kotono a brief period to establish her own space, but his sudden reappearance threatens to upend everything she has grown used to. With him back under the same roof, the familiar weight of his influence settles over the household once more. Now, Kotono must confront the reality of sharing her life with the sibling who has always eclipsed her. As old dynamics resurface and new tensions emerge from his long-awaited return, she is forced to question what will happen next. Will she continue to fade into the background, or will this unexpected reunion finally push her to step out of his shadow and forge her own path?
