Human psychology could be weird at times. When person A couldn't stop forcing person B to do something they didn't like, person B would always refuse and feel disgusted, and person B would not want to do something they despised if they were forced all the time.
However, if person C suddenly appeared like a gentleman who didn't want to force person B to do something they didn't want, person B might feel sympathy for person C, and they might even offer to do something they didn't like out of sympathy.
It was uncertain whether such a thing could be said as sympathy or pity, but Bai Chen finally offered himself to help Wu Jinhai after seeing how the man looked like a gentleman as if he didn't want to force Bai Chen to do something he didn't want to do.
