Every day, we are burdened with more or less pressure and responsibilities to live in every corner of the city. Sometimes diaries can become the object of countless people's talk. The secrets that you don't want to share with others, the scars from the past that you don't want to reveal, and the memories that cannot be washed away by time, are all poured into the diary and quietly hidden by the years. Su He is also such a woman. She carries a heavy past and struggles tiredly in the cage of memories. The angelic girl that everyone once boasted about was reborn in hell because of one person, one city and one story. During the 1497 days of thinking about you, what happened in the past life, and whether these long days ended and freed Su He's riddled heart, or will still be waiting for her in the unknown years... We will eventually get the answer in her diary.
