Oh No! Their Son's a Billionaire!

Yasuko and Shoichi had been married a long time, and Shoichi had dementia, so on the cruise he kept trying to shield her even when he was barely aware of what was happening. The trip was for their anniversary, by ship to Nagasaki. Their son had arranged it and offered the guide, Risa, a promotion for looking after them. Risa saw their plain clothes and took them for poor. She treated another couple in showy fakes as the chairman's parents and pushed Yasuko and Shoichi around, insulting them. Yasuko said nothing at first. Their children Hayato, Haruki and Misaki stepped in. Yasuko and Shoichi owned the largest group in the country.
