[Upcoming historical romance, please add to your collection] Blurb 1: Shi Run is threatened with her elder brother's life and given two choices. Become his concubine, or sneak into the palace asylum and kill the madman Mu An. Shi Run looks at the man before her, Su Yunqing, the current chancellor, and remembers that in her previous life, she chose to become his concubine. He favored her, then abandoned her, and she died miserably at the hands of his other women in the chancellor's residence. Reborn at the moment of choice, she decisively chooses the second path! Blurb 2: Everyone knows that the former crown prince, Mu An, is cold by nature, ruthless, and a demon in human form. The mere mention of him makes people tremble. Later, Mu An bathes the palace in blood and reclaims the throne. Everyone thinks Shi Run is doomed, since she once trampled him underfoot and tried to kill him several times. Shi Run thinks so too, so she fakes her death and runs away. But this time, Mu An seems to have truly gone mad. He abandons his harem to find Shi Run, then drags her back and confines her in the palace. Under the night sky, he lifts her chin and brushes his cool fingertips over her skin. "What if I pamper only you in my harem?" Reader's guide: 1. The male lead isn't mentally ill, but he really is a madman, and he really does use force to take what he wants. 2. There is no vast imperial harem. 3. Happy ending. Theme: There is always a ray of light in the darkness.
