Question

who was Hana and where sadao meet her how
were they married

Answer 1

Hana and Sadao met in USA, while finishing their higher studies. A professor at the college called some of his students to his place for a dinner and to make them comfortable. It was love at first sight for Sadao, but he didn't try to make a move till he was sure that Hana is a pure bred Japanese. This was due to his fear of his father. His father believed that only Japanese were good and not Americans. Soon they got married after the father's approval and relocated back to Japan .

Hope this helps :)
