Amane Nakanose's mother is planning to remarry, and thrilled at the prospect of gaining a younger brother, Amane gives her wholehearted approval. However, when Naoya Akasegawa arrives as her new sibling, he is nothing like the little brother she envisioned—he is only three days younger than her. Likewise, the older sister Naoya had dreamed of turns out to be far from what he expected. Confronted by chilly indifference and the insistence that he call her "onee-chan," Naoya attempts to adjust to life with his new sister. Yet despite Amane's proud attitude, he can't help but glimpse the kind girl underneath. With renewed optimism, Naoya resolves to make the most of their new family.
