What did Sachi plan to do after learning she had leprosy?

Sachi tells Stephen that she had brought dishonor to her family by contracting the disease and that she planned to join several others in suicide on a particular morning to restore her family's honor. When the time came, she watched others kill themselves but couldn't bring herself to do the same. Instead, she ran away and was found by Matsu, who helped her settle into the village of Yamaguchi with others.
