His father remarried. His son Kota was happy about his father's remarriage, but in Kokoro he was suspicious of his new wife, Wang, who was a mismatch for his father. This was because he knew that Wang was not only incompetent at housework, but also had a wrong sense of money, and would sneak out of the house after his father left for work, putting on makeup. Kota tried to suppress his Kokoro, not wanting to ruin his father's happiness by prying into her affairs, but the situation ended in an unexpected way.
