Live for me, won't you?

Seven years ago, three out of four nations in a continent were merged into one by the notorious young empress of the east, Mu Feng. She, who conquered the north and south, was then eventually killed by her own familiar whom her heart wholeheartedly trusted.

After roaming the underworld as a lone spirit for seven years, she attempted to transmigrate back to the human realm.

However, an accident happened!!!

Her soul unwittingly possessed the body of Yu Xiao, Crown Prince of the kingdom ruling the west. Where did it go wrong?

What's worse was the person who killed her- the one she, who was now a 'he', wanted to avoid the most kept on crossing paths with him. But were those encounters really nothing but coincidence?
