Susan was worried about Cassie and what she would think of her staying with Jack. She knew that both Jack and Cassie were boyfriend and girlfriend and on top of that Cassie hated her.
Previously, whenever she tried to talk to Jack in the presence of Cassie, she noticed Cassie's secret anger and jealousy.
"I think, I can stay on my own." Susan averted her gaze from him, for some reason she was ashamed of looking at Jack.
Although she has already been intimate with him and even lost her virginity to him, she still felt like she has done something bad to him.
'Maybe I shouldn't have asked his help, he must think I am crazy now.' Susan remembered her previous words.
She knew it was difficult to believe in ghosts, and even if she had been in Jack's shoes, she would not have believed a story like this.
She might have even made fun of Jack if he was the one telling the story.
