Tadaaki became intensely interested in Yumiko, his father's new wife, and arrogantly exploited the fact that she depended on financial support from his father, manipulating her to obey his desires. He also forced Yuusaku, Yumiko's son, to accept less affection than himself, completely ignoring the boy's feelings. One day, Yuusaku witnessed his mother being molested and, in a fit of rage, attacked Tadaaki. Feeling isolated and hurt by the growing emotional distance from his mother, Yuusaku fell into depression, alone in his room. At that moment, his mother appeared and revealed the truth, and the two embraced. Then, a new beginning arrived.
