In life, people are constantly leaving or entering.
So, what was seen was lost; what was remembered was forgotten.
In life, there are constant gains and losses.
So, what is invisible is seen; what is forgotten is remembered.
However, if it is invisible, does it mean it does not exist?
Remember, will it never disappear?
Xiao Jing, you won't leave me, right? You said, if we depend on each other, don't leave me!
