Saya appears to be a perfectly ordinary schoolgirl in almost every respect, save for one glaring exception: she harbors an overwhelming and deeply concealed infatuation with her older brother. Despite the intensity of her feelings, she remains entirely incapable of expressing her affection or making any meaningful romantic progress with him. Her inability to be honest about her emotions manifests in a rather destructive way, as she routinely resorts to physically assaulting him whenever they cross paths, effectively ruining any chance of growing closer. However, her frustrating daily routine takes a bizarre and unexpected turn when she suddenly awakens to find herself inhabiting the body of a cat. To complicate matters further, this feline form happens to belong to a pet her beloved older brother has just brought home. Thrust into this surreal situation, Saya is presented with an unprecedented opportunity that completely bypasses her usual inability to show vulnerability. Now living under his roof as his new pet, she must navigate this strange predicament and determine whether this accidental transformation might finally be the key to capturing her brother's heart.
