Jiang Jiu's psychological issues came about after Grandma Jiang passed away.
During that time, Jiang Jiu and Jiang Siyan were still apart, so in her most painful moments, she was almost entirely on her own, which also caused her psychological pressure to grow.
Zhu Yixue had conducted therapy with Jiang Jiu a few times and found that she was still trapped in the scene where Grandma Jiang was killed, unable to escape from it. She would be terrified by large splashes of red liquid, which reminded her of blood.
There was also the last phone call Grandma Jiang made to her from the studio. Jiang Jiu didn't realize the danger on the other end of the call and hung up quickly due to work. These were the demons in Jiang Jiu's heart.
Even though Ge Hongcheng was already dead, the demons in Jiang Jiu's heart hadn't disappeared.
Later on, after Jiang Siyan's accident, Jiang Jiu's insomnia became more severe, and she stopped going to Zhu Yixue's psychology office.
