Hell's Handbook - Chapter 1: Hell’s Handbook

Le Wan transmigrated into a book, becoming a sacrifice in the fight between a real rich daughter and a fake rich daughter. Being the cousin of the real rich daughter, she had a good family background and looks, as well as the affection of all other family members and her fiance. She is unquestionably the object of group pampering, treated like a princess, and born lucky… She would have been a winner if she had not sabotaged herself.

However, the problem was that her fiance was the male lead! A philandering scumbag, he would always call Le Wan ‘darling’ before the female lead showed up, stealing the cousin’s heart. However, once the female lead appeared, he started calling her ‘sister’ instead and distant himself, insisting that he was loyal to the female lead. Being lovestruck and having been pampered since birth, Le Wan’s original body could not accept being dumped for the rich daughter, who was raised in a farming village! She decided to endlessly harass the female lead, reducing herself to cannon fodder and subjecting her whole family to the same fate.

However, Le Wan was her own person, and she would rather stay pampered by her family and live with them happily ever after. Male lead? That piece of trash? He belongs in a trash can! I have no feelings for him at all! The rich daughter tried to frame her to get the family’s affection and use her as a tool? Sorry, but I don’t live in a dog-eat-dog world as you do. Bring me my popcorn. I will watch them tear each other apart! The ice-cold villain? Stroking her chin and smiling like a shrewd fox, Le Wan said: Oh, poor you… Come to me. I will pamper you lots. The villain who was receiving lots of cuddling: What happened? Who am I? Where am I?

Qiao Zhenzhen spent a lifetime, only to later realise that she was the true heroine of a novel. According to the original plot, her life was supposed to be smooth sailing and blissful. But the envious transmigrated second female lead played her cards step by step, and took everything away from her!

After experiencing the divorce of her parents, and miserably failing the college entrance examination, she gets kidnapped along with her little follower of a male lead, Chi Shen. In the end, she came out as the only survivor.

Everyone believed that this was a blessing in disguise, not only was her life saved, but the pervert stalking her for the last three years was also gone! A freak like Chi Shen, who had a weird and eccentric personality, always stank of fish and grease, was better off dead. Everyone said that she ought to be grateful, but none of them knew he died protecting her.
Before he took his last breath, his dying words were-

“Don’t be afraid of me.”

That sentence, mixed with the smell of greasy fish and blood, flashed in her dreams every night for the next decade.

Reborn back into the senior year of her highschool, she walked to the youth in the corner, and in front of everyone’s eyes-

“Don’t hideaway in the dark if you don’t want me to be afraid of you.” The youth pursed his lips, his pale face steadily losing color.

Qiao Zhenzhen smiled: Be nice to me, and I shall allow you to stalk~
