His and Her Circumstances Season 1 Episode 13

Subjective Happiness

Tsubasa is opposed to her father's remarriage, but soon relizes that her opinions carry no weight. So she gives in and agrees to meet her stepbrother-to-be, who turns out to be a blond punk rocker named Kazuma. His remarks burn Tsubasa and everything goes right to hell! Later, they meet by chance in the street, with very different results. They realize they're the same kind of child brought up by a single parent with similar background. Tsubasa eventually accepts Kazuma and hence, Hiromi, the stepmother.
