Change your face, return to your old place after losing your memory, and find your own story. What novel do you recommend?

The female protagonist was changed, changed her identity, lost her memory, and returned to find herself!
General content:
The female protagonist was saved by her master and changed her identity (the real person with this identity is still alive and made a life-saving deal with her master. She can't tell the truth. PS: Her master's life depends on her mood and the conditions of the exchange). And there seemed to be a wild beast pet, like a white tiger? After living for a period of time, he would go down the mountain and integrate into his identity.
The opening was about the female protagonist playing with this little pet in the snow (I don't know if there's any cross content)
The female protagonist always knew that the male protagonist was deeply in love with a goddess (in fact, it was her before she changed)
He couldn't remember the details, but he knew that it was very good…
The female lead's name seemed to be Su or Qing…
Female N, whose identity had been changed, could not help but tell her family that she was still alive, but her family did not dare to believe it…
It seemed to be the work of a famous artist…
There was too little content in the book, so he begged the gods to give him a title!

Answer 1

The heroine was originally a princess who was married to a man who didn't care about her at all, but she was saved by him in an accident. From then on, the female protagonist followed him on the expedition. The two of them slowly got to know each other, and the female protagonist gradually learned about her background and the dangers she faced. This book was an ancient romance novel. I hope you like this fairy's recommendation. Muah~😗
