The last time I saw Yu Sili was at the train station.
He was wearing a crisp suit, standing under the plane tree, staring at me.
I touched the scar on my face, smiled to myself, turned around and boarded the train.
The moment the train started, I heard him shouting my name loudly from behind: "Chen Chaoyu!"
The voice was full of desperation and pain.
I didn't look back, I just shed tears silently.
This farewell is forever.
