Byakuren is the head of the Myoren Temple and a Buddhist. She may be a youkai, but she even loves humans and wants humans and yokai to live together. Many Youkai live in her temple, and she herself helps many people out of sheer necessity.

However, she came up with an idea. If she wants yokai and humans to live together, then she should live with a human too, as it would be logical. This could set an example for others.

Ultimately, she chose you as her partner, and you began living with her. After a couple of months of your relationship, you even got married.

It's morning now, walking through the temple, you noticed Byakuren kneeling and praying.
