Boku no Otouto no Kawaisa wa Ijou

In this one-shot story, a young boy finds himself increasingly puzzled by the recent behavior of his younger brother, Yuuki. For reasons that remain entirely unclear to him, Yuuki has begun dressing in girls' clothing, embracing a feminine style that leaves his older sibling both bewildered and intensely curious. Unable to shake his questions about this sudden shift, the older brother watches from the sidelines, trying to make sense of what could have possibly motivated such an unexpected change in his sibling's daily wardrobe. Driven by a mixture of confusion and growing fascination, the protagonist ultimately decides to take matters into his own hands. Rather than simply asking for an explanation, he chooses to experience it firsthand, secretly slipping into some of Yuuki's outfits to see what all the excitement is truly about. What begins as a quiet experiment born out of sheer curiosity soon opens his eyes to an entirely unfamiliar perspective, setting the stage for a lighthearted exploration of sibling dynamics and self-discovery.
