Night Conceals the Fragrance

A modern-day, tsundere special agent transmigrates into the body of Qin Ziye, a sickly young lady in ancient times.

Qin Ziye's birth killed her mother, making her a thorn in the side of her lovesick father. She grew up gloomy and cautious, and fell ill with longing after falling for her older sister's lover. Just as she was clinging to life, her soul transmigrated into the body.

Living a second life, Ziye suppresses her "innate" attraction to her future brother-in-law, ignores the family head's "habitual" cold remarks, and sidesteps the modern values that demand she rise to the top after transmigrating. She declares that she's going to live a comfortable life of her own choosing.

Qin Ziye: Heh. This is the comeback story everyone is fighting over? (Tosses it aside.) I don't want it. I want to lie down and still make it to the top.

Male lead: (Lies down seductively and pats the bed.) My life is yours.

[Heroine] Versatile, sweet, fussy, laid-back, calm, nonsensical, fickle, and in love or out of love depending on her mood x [Hero] Abstinent, sexy, otherworldly in appearance, venomous at heart, neither wholly good nor evil, with a split personality and a few screws loose

P.S. 1. Most official positions are based on a fictionalized Ming Dynasty. All other details exist to serve the plot, so please don't nitpick them.

2. A slow-burn story with light wuxia and light power-fantasy elements. If you like protagonists who start out maxed out from the start, this isn't for you.

Theme: When women stand on their own, the world is wide open.
