Parallel Time Diary

Xu Nin and Qi Jingzhi, who had known each other since high school, went from bickering rivals to lovers. She was resilient and brave, while he was gentle and optimistic. Together, they made it through the college entrance exams and a long-distance relationship throughout four years of college, going from school uniforms to wedding attire. He taught her to embrace happiness and open her heart. But later, after his family suffered a dramatic upheaval, the once-gentle, bright young man bowed to the pressures of life and became an ordinary middle-aged man consumed by making ends meet. His coldness and distance brought their relationship to an end, and he and Xu Nin grew further apart until they finally chose to divorce.

After the funeral, as she clung to his grave and wept, a woman claiming to be a distant relative, Seventh Madam, gave Xu Nin a box of calming incense. She told her that if she truly wanted to, the incense could give her a chance to change the past.

That night, Xu Nin returned to her old family home and lit a stick of incense. Everything around her changed, and she found herself back in the same place twenty years earlier, on the first day she was about to start high school. She watched her younger self leave the house, then greeted and smiled at the woman she had once regarded as a stranger. She witnessed her first meeting with Qi Jingzhi. She thought she had simply traveled back in time, but when she woke up, she discovered that her middle-aged self had appeared in an old photograph, and her memories of meeting Qi Jingzhi had changed as well...
