The Mad Regent Is Fierce by Day and Sweet by Night

(Both leads have no romantic history + Female lead transmigrates + Male lead is reborn + One-on-one romance) Shen Yunzhu transmigrates into the legitimate daughter of the Shen family and is forced to marry an unhinged prince. She’s being tormented from the start. But she has a cheat, so she doesn’t panic. She heals the sick, saves lives, removes poisons and curses, and takes down scumbags and weaklings. Her ultimate move is to shut the door and let the prince loose. The reborn madman only wants revenge: “Don’t think you can climb into my bed. Women will only slow down my revenge!” Later... The regent, whose name once struck fear into the entire court, warms her bed every night. “My lady, don’t move. I’ll carry you over.” A gentleman’s revenge can wait ten years, but there’s no time to waste on consummating the marriage and having a baby!
