Some people's hearts are originally kind and soft, but after experiencing betrayal, they have nothing, or even die. No matter how soft your heart is, it will be slowly eroded and grow a hard and ugly shell. Only with such a heart can we live long and live to the end. But underneath that shell, that heart has actually never changed.
The truth is revealed layer by layer, and the destiny is arranged. There is no way to escape, and I don't want to escape.
Concept: There are always pros and cons in everything. The more perfect something looks, the uglier it is behind the scenes...
