Human beings were stubborn and selfish by nature. One's own desires always prevailed over the desires or needs of others; it was very rare for a person to be willing to sacrifice their own happiness for the good of others.
Human beings were emotional beings. Each person's emotions generally dominated over the brain and logic when the heart took the lead.
Because human beings were stubborn, selfish, and emotional by nature, no man or woman would be happy if the person they loved, with whom they wanted to spend the rest of their lives together, was with someone else... The phrase "if she/he is happy, I am happy" was only valid for fantasy tales; the real world was cruel.
None of the men present were willing to accept Shen Xinya's words easily.
