(Complete, come on in) [Sweet romance + a touch of fantasy + love that grows over time + unconventional ancient-style rebirth + mutual devotion + powerful leads, with a strong female lead]
Secondary couple: aloof and refined bottom x scheming, long-suffering top (not for you if this bothers you; they don't take up much of the story)
[Kindhearted, people-loving, cunning Crown Prince x cool on the outside, warm within, bold and dazzling female general]
Top assassin Jiang Jin has been reborn! Or has she? She's arrived in a world she doesn't recognize at all!!! To fulfill the original owner's wish, she investigates her father's death step by step, only to find herself drawn into more and more secrets...
Her identity, her stepmother's true face, and that... icy Crown Prince...
*
On the battlefield, she is a glorious female general who kills anyone who stands in her way, a demon feared by all. Clad in red, she guards the southern frontier, and from then on, no one dares invade.
But during one battle, a traitor in the army leaves her trapped, and her whereabouts become unknown. Everyone thinks Jiang Jin is dead. The powerful ministers at court secretly rejoice, glad that the military leader is gone. The whole empire celebrates the death of the battlefield demon. Only the Crown Prince, usually cold to everyone, rushes to the southern frontier in a frenzy that very night. After searching day and night, he finally finds Jiang Jin, barely alive, in a cave. The Crown Prince, who never shows his feelings, has red-rimmed eyes that day... and weeps...
The Crown Prince fears neither gods nor spirits, yet he is willing to kneel without rising in a Buddhist temple, praying only for her safety.
“I often wonder when I first fell in love with you. I have many answers, but none of them feels quite true.”
The writing is very, very good.
