As a fat, sickly, and spoiled child, Takefumi was constantly picked on in elementary school. He was somewhat protected by the tomboy Tsubaki, who, while protecting him from other bullies, would bully Takefumi herself. When he asked Tsubaki why she paid attention to him, she told him that a teacher had asked her to look after him. After hearing this, Takefumi is humiliated as he had never been in his life; he is humiliated because he had believed that he was somehow special to Tsubaki, but he realized that she did not care about him at all, and was just obeying a teacher's request.
