Can you recommend some good urban killer novels with cold-blooded and ruthless protagonists?

Keeley, a simple plain Jane, hits the jackpot. [No, she did not win the lottery!] At least that's what she thinks when she marries the most eligible bachelor in New York City: Aaron, a wealthy cold-hearted heartthrob and Tycoon. She wants to show the world that she deserves her position and bends over backward to fit into his world. One beautiful day, Aaron hands her a document asking her to sign. A divorce paper... "She's pregnant, and I need to take responsibility." That is the last thing that keeps on playing in her mind before she takes her last breath. Keeley dies, a 'hit and run'. [End of story. Not!] For some unexplainable reason, she wakes up as her younger self. A young high school girl, around the time when she first meets her cheating husband. Remembering her life with Aaron before she died, she makes a promise to herself that she will do everything in her power to avoid him at all costs. Will she be able to keep her promise when Aaron has his own plans as well, specifically for her? Or will she repeat history and fall for him once more... Why not journey with me and find out the truth behind their story. *Cover art by polkadottedscrunchie*

A man that doesn't know his past, except for specific memories, was suddenly throwed on a weird but familiar world, in a dangerous situation. And now he has to survive in this world without any guidance but a system that came out of nowhere. Read the Tags. I placed a lot of Tags that has mature content as this novel will be full of spicy lemons. But, of course, it will have plot as writing too much lemons is mind tiring. Have a good time reading it. Also, if you see mistakes at the beginning, don't worry, it becomes better as you read. If you understand me.( ͡° ͜ʖ ͡°) All the rights of the works I may use as reference are from the respective Authors, with the exception of my OCs. Also English is my third language, so forgive me if you see many mistakes or chronological errors.

Voted as the most funny and shameless fanfic on WebNovel.
