“After my wife’s death, I unexpectedly returned to the time when he secretly loved me, and I was unaware.” Li Chishu has attempted su*cide numerous times over the years, and I have consistently been there to pull him back from the gates of hell. However, I never anticipated his determination to leave this world would be so strong. One night, when I wasn’t keeping a close eye on him, he finally jumped from the building. I wasn’t able to pull him back in time, so I could only sleep at his funeral. When I woke up, the surroundings were filled with noise. I found myself standing in the school building from ten years ago, and someone from the next class informed me that Li Chishu was having a physical education class on the sports ground.
