Before, she was a modern age demoness, striking fear into people's hearts, the eldest miss of the Shang family. Under her boundlessly splendid appearance was hiding a cold as ice heart.
Now, she is the cowardly and gravely ill crown prince Shang Wuxin.
Just as that cowardly Shang Wuxin died, the body welcomed a brand new soul, Shang Wuxin (heartless). Heartless, and also ruthless, cruel like a devil. When she changes into her, when cowardice changes to cruelty, when ignorance changes to wisdom, when kindness turns into bloodshed, whose eyes has this kind of woman caught? Whose heart has she stolen? When she stands at the peak, who will come and hold her hand to end her loneliness and desolation?
TL's summary: After getting betrayed by the only person she'd loved, and dying, miss Shang wakes up in the body of the cowardly crown prince Shang Wuxin, who is actually a girl cross-dressing as a boy due to her own circumstances. After inheriting the crown prince's memories, Shang Wuxin has three things on her agenda:
1. Clean up house
2. Gather loyal followers and soldiers
3. Get the throne
