What should be the best ending for the story of the soul of the great bell?

In the end of the soul of the great bell, O-Yuki asked Minokichi about the White Woman, of which then they explained about the night in the fisherman's hut. It was then that Yuki claimed it was her and threatened him if the children should ever complain about him. That is when she melted away turning into a mist that dissolved into the roof beams, never to be seen again.
