How to Promote the Darkening of the Male Protagonist

— Wen Ling was born mediocre and free from disasters and illnesses. Since childhood, she has only heard about the magnificent lives of others. Her only luck was that she got to read a popular romance novel. The female protagonist of this book is a noble girl from a famous family, and the male protagonist is the chief of an immortal sect. The two are a perfect match, creating a rare marriage. However, this is a dark story about chasing a wife under the skin of a double-brother. The only good fortune turned into misfortune. Wen Ling was the vicious female supporting character who framed the heroine and was blackened by the hero before being killed with a sword. Since it is destined to be like this, then take it one step at a time. As a junior sister, she followed the male protagonist through mountains and rivers, watching the tenderness reflected in his clear eyes, watching him sleep on the stone with flowers, and watching him carry a sword for the heroine to settle the grudges. Wen Ling followed in the footsteps of her original self and fell in love with the male protagonist, but there was no cure. She was so lost in her thoughts that she almost forgot how bad her luck was until the ending caught up with her. The night was silent, and the pear flowers all over the mountain withered because of the male protagonist's demonic fall. He was stained with blood and held a sword in his hand. Before being stabbed through the heart by a sword, Wen Ling took one last look at him. She thought sadly that she was thousands of times stupider than her original self. — The chief disciple of the Yueshan Sect fell into a demon state and was publicly tried by the Immortal Alliance. His evil soul was removed, his bones and soul were cleansed, and he was punished with 3,900 lashes of an immortal whip. He finally redeemed his murderous karma and announced it to the world. But the world doesn't know that the evil man once had a junior sister. Junior sister is childish and always pesters him, singing marriage proposal songs and sending wedding bells, day and night. Since the death of his junior sister, he has always fallen asleep. I'm most afraid of dreaming about her. I am most afraid of not being able to dream of her. Thirty-nine hundred lashes are no more painful than a dream. Huo Zhifeng has been cold and unrighteous throughout his life, and has never believed in true love. Only towards Wen Ling, he always loves tenderness. — Later, Wen Ling looked at the man hugging her with his eyes closed, and thought to herself, this is indeed a story about chasing a wife. Wen Ling whispered: "Why are you shaking?" Huo Zhifeng's voice was hoarse: "... You can go with him, as long as you cut off my head with your own hands." But it's her who's chasing her? — Tips before reading: 1. HE, SC. 2.
