Explain why Nishima is staying in the Takeda home?

Kenji Nishima is first introduced when he is shamed by the actions of his boss, the superintendent of the Sunday school at Taro’s church. Kenji, a seminary student, is overwhelmed by the guilt of the superintendent’s actions, as well as by the responsibility as a student and as a practicing leader of the church. He is lonely and homesick, not psychologically or physically well. Hana suggests that she and Taro take Kenji into their home so she can nourish Kenji back to health.
