"The day I found out you were dead was the first day I started falling in love with you."
23-Year-old police officer x 16-year-old boy Bai
Han Xin, a 23-year-old police officer who had just graduated and joined the job, encountered a case. The deceased was his first love in high school. However, he had very vague memories of that period and never liked this first love.
The night after visiting the family of the deceased, he traveled back to his 17-year-old self and met the young man who was about to confess his love to him, Li Bai.
After time and again traveling back to six years ago, Han Xin gradually understood that this was a closed time loop, and he needed to save Li Bai before his death date came.
Concept: The young couple is sweet and at ease
