Why doesn't sharping ghost hurt mistress?

Shaping's ghost doesn't hurt the heroine Siji, because she is her family.

When filming The Shining, Jack Nicholson, the hero, said that he could at least get enough respect on the set, but Sheryl Duval, the heroine, was not so lucky. Nicholson and Duval played a couple in The Shining, and they spent the winter together in Panorama Hotel. However, in this remote and isolated place, Jack played by Nicholson began to behave strangely and gradually lost himself. Finally, he even caught up with his wife and personally created a family tragedy.

In this story, Nicholson's character gradually becomes obsessed, while Duval's character gradually collapses. For Kubrick, he needs a perfect collapse to show how terrible the madness of the writer's husband is. Kubrick, who once insisted on shooting indoors through natural light, certainly had different requirements for authenticity-he was different from ordinary people in many places. And he needs a broken heroine, so he has to break Duval himself first.
