There were a few romance novels with a cold female lead and a black-bellied male lead. They were "The Unscrupulous Young Master: The Adorable Wife Rulers Her Husband Every Night","The Evolution Theory of the Evil Boss in Quick Redemption","The Evil Prince Loves His Favor: The Crazy Concubine Is Too Black-bellied","The Evil Concubine Reborn in the Apocalypse","The Crazy Phoenix Defies the Heaven: The Dark Lord's Supreme Wife","The Adorable Concubine of the Rich Prince","The Book Traversal: Abduct an Assassin to Be Her Husband","Mr. Quan Is a Little Naughty", and so on. I hope you like my recommendation. Muah ~
