Favored for a Lifetime

I don't know whether it's luck or misfortune. I can travel down the stairs. I just came to this strange world, but I was full of hatred. I was forced to marry a prince who was about to die. No matter if he was going to die, at least he must live for me now. I tried my best to cure him, but accidentally lost my heart. What should I do... He has more power than the emperor, more influence than the palace, and has unfathomable martial arts. So what, there is one more me in the world, but what should I do with this little woman who has saved me wholeheartedly? Why do I feel better the more I dote on her? What should I do if I don't dote on her one day and I get bored and panicked...
