What is the knot of the same heart? Take a bunch of hair from both lovers and tie it into a flower knot. It means to have the same heart and the same virtue, and to seal the love for three generations.
How can a twelve-year-old child understand love? However, when she stayed in his dream for eight years and never left, he clearly understood that she was the woman he wanted to marry. Even though the woman around him had the same face as her, she was not the person he was looking for, and she would never be.
Of course she was not willing to be a substitute. She loved him so much that even if she had to turn her back on the world and give up her life, it would not be a pity. How could she bear it, that she was actually her sister's substitute?
Can the blood-stained concentric knot lock three lives again?
