What is the curse? I can't understand it after reading it several times.

The story mainly tells that "curse" is the curse of people who die of resentment. A strong resentment generated by people's inner anger after they died in vain will exist in the place where the deceased lived for a long time, forming an evil dark force with a curse and accumulating resentment in the place where the deceased lived. Anyone who touches it will die, creating a new "curse" and spreading terrible deaths. The "curse" will always stick in the haunted house.

Introduction-

Kayako was a lonely and eccentric girl since she was a child. Growing up, she had no friends, only a black cat accompanied her. When she was in college, she liked Shunsuke Kobayashi. She recorded everything about Shunsuke Kobayashi in her notebook. But in the end, Kobayashi Shunsuke fell in love with other girls in the class and got married. Kayako later married Saeki Xiong Gang and gave birth to a son named Xiong Jun. Kobayashi Shunsuke happened to be his teacher. Saeki Xiong Gang wants a second child, but he can't.

After going to the hospital for examination, I learned that I had oligozoospermia and the survival rate was extremely low, so I suspected that Xiong Jun might not be his son. When I got home, I found Kayako's diary about Kobayashi Shunsuke. I couldn't help being jealous, and Kayako was tortured to death. Kayako's childhood loneliness, depression and resentment produced a curse at the moment of his death, which lingered in this house for a long time.

The story begins here. The main clue of the "Curse" series is how the curse of Kayako and Xiong Jun affects everyone who walks into this house. No matter who he is, where he came from, where he went and why he walked into this house, no one who touched the curse could escape.
