Meng Wan has never met her father, and her mother has told her since she was a child: You have to make it to the end, and you can't be worse than anyone else. Therefore, she has never told anyone about all the hardships she has endured.
Later, she met a man named Shen Junyan, and for the first time someone told him: If you are here, I will be there. If you are willing, I will stand by your side; if you are not willing, I will always protect you.
She knew how to break the shackles.
For Shen Junyan, Meng Wan is the light of his life. You give me a candy and I will protect you for the rest of your life.
Concept: Everyone has shackles, but you have to find a way to open them.
