My name is Lin Runzhi, an ordinary delivery boy.
Until that day, I picked up a tin box. It can save people, and it can also kill people - the price is that every time I change the cause and effect, I will be forgotten by the world.
Now, my grandma doesn't remember me, my mother doesn't recognize me, and the person I tried my best to save says "hello" to me.
I became a person deleted by the whole world.
