Please recommend a classic romance novel about a one-on-one man and a woman. Don't be too simple and easy to understand.

😋I recommend the following novel to you: - "The All-round Useless Concubine": The female protagonist is the 21st century's King of Assassins, the Evil God, who has transmigrated to become the Murong family's Useless Seventh Miss. Men are strong, women are strong, one-on-one love text. - "Evil Prince's Pet: Fierce Concubine, Don't Flirt": The female protagonist is cold and aloof. She unexpectedly explodes with her spirit-gathering physique. She is chased by everyone in the world. She meets the male protagonist. The male protagonist is suspicious by nature, but he is interested in her. It was a one-on-one fight between the strong man and the strong woman. - "Seventh Missy of the Heretic Doctor": The female protagonist is a famous Chinese doctor. She is schemed to death and her soul transmigrated into the male protagonist, the useless young master of Liuli. The male lead was the mysterious Han Wang, and the way the two met was a little strange. Men are strong, women are strong, one-on-one love text. - "Emperor Stand By: The Godly Doctor Crazy Concubine Is Going Against The Heavens": The female protagonist is a top military doctor of the 21st century. She transmigrated into the body of a useless young lady and met the male protagonist, the Imperial Advisor of the Heavenly Kingdom, Yan Wuchen. The male protagonist is cold and evil, but he treats the female protagonist differently. The male is strong and the female is strong. It's a one-on-one love story. - "First-grade Trash Concubine": The female lead was a genius who turned into a good-for-nothing. She died for three days and came back to life. She was beautiful and ruthless. The male lead was a prince who regarded the female lead as a treasure. It was a one-on-one fight between a strong man and a strong woman. - "Love You Addict: The female protagonist transmigrated to become the Fourth Miss of the General's Mansion, who was not favored. She was the god who controlled the world's number one assassin organization. The male lead doted on her like his life and loved her to the bone. Men are strong, women are strong, one-on-one love text. The above is my personal recommendation. I sincerely hope you like it ~
