Born over a tofu shop in Osaka, twin sisters Reiko and Kyoko have very different characters. Reiko is diligent, and longs for a secure, middle class lifestyle. Kyoko is a free spirit, who seeks thrills and adventure. We follow them on a roller coaster story of love, marriage, birth, triumph and disaster. This drama is compelling both for its human interest and for the way it charts the tumult of modern Japan.
