Many times, An Chefeng would wonder whether his decision was right or wrong. Shouldn't he do this sometimes?
But in fact, more often than not, he is doubting,
Doubt whether I should exist
In other words, I doubt whether I really exist.
Maybe many people are like this. Once you have been hurt once, even if times have passed, your soul has been marked with the scars of that time.
No matter how many years have passed, it's just a good thing.
And the wound on An Chefeng's soul was abandonment...
Because that actually means that everything in your existence has been denied.
