Ning Yuan was a specially made hollow doll. Her chest was empty, and her heart was hidden in her bone marrow. When Su Heng held a heart close to her, her chest was bleeding, but her heart was beating.
When the blood in her chest was about to drain out, Su Heng put his heart in, so Ning Yuan's chest stopped bleeding, and the heart hidden in the bone marrow began to sleep.
The nine-tailed fox is neither human nor demon, neither fairy nor demon. God gave Su Heng an unparalleled heart, but cursed him to lose his love forever if he used it.
Purpose: Loving yourself is the best way to love others
