Exclusive Possession of Your Heart

I was given a second chance at life with this transplanted heart, but I have also lost my freedom because of it. Di Zigang, the man who wanted me to take his late girlfriend's place; Wei Rufei, my doctor and childhood friend who sacrificed everything to save my life; and the sister of the heart donor. One transplant operation tied four people together. How will I be able to bear all the emotional baggage attached to the original owner of my new heart?
