Is There A Good Example Of A Mary Sue/Gary Stu?

I'm reading a book about a boy who bullies a girl, but they end up in love? Screw that; if it were me, I'd ruin the plot.

As the male lead, Henry Johnston, forces himself on me, a row of comments suddenly appears before my eyes. "Henry is about to misunderstand and think Aria drugged him! The angst is about to begin!" "I'm thrilled just thinking about Henry regretting dearly after Aria dies!" "Keep up the act, Henry. After she dies, you'll be hugging her corpse and crying every day." That is when I realize that I am the tragic female lead in a story where I am destined to be tormented until I die. The readers treat my death as a highlight to push the plot forward. They are counting down to my death. As I look at Henry, who is panting on top of me, anger courses through me. I grab a table lamp and smash it into him, killing him on the spot. Who says that the one who dies in a toxic romance story must always be the female lead?

Domenico Pietro de Cerintti, in the eyes of everyone was the good boy, the sacrificial lamb, the one who attended all the classes and obeyed all the rules, the one who would not let a puppy get run over by a car, the one who didn't have a girl in his bed every Friday night, the one who didn't smirk, the one who girls liked but never wanted, the one who girls used and dumped, the one who wasn't badass. He lived with that image, was content with it even with the bullying until a certain day when they crossed the line, the one line they were never to cross. He disappeared. And appeared months later, in college; the college that had a good percent of his highschool student in attendance; changed, for the worse. Rosetta D'armani, one of his mates in highschool and now his mate in college, who never bullied him but who also never saved him from the bullies. She was, as defined by the male folk, hot, sexy, drool worthy. She saw him on his first day back and lusted after him. She followed him, sought after him, chased after him with every breath in her. He made her lick his heels. After all he was badass now. He smirked now, he had girls in his bed not only every Friday night but every night, the girls wanted him, he used and dumped them now, he was badass. But oh...those bullies didn't know his definition of badass. Badass for him meant revenge. He would revenge on each one of them including his beloved girlfriend. He'd show them just how hot badass burned. One mysterious girl, one desperate girl, one perfect girl and one revengeful boy. ???

After transmigrating through three novels in a row, the hardest thing I ever suffer through is drinking iced long black. But when I open my eyes again, I somehow become the pathetic simp side character in a trashy romance novel. Just as I debate whether to file a complaint against the system, the trembling system hurriedly explains something to me. Although this is a trashy romance novel, it is also an unfinished abandoned novel. I ask, "So you're saying I decide how the story develops?" The system replied, "Yes. Everything is completely under your control." Satisfied, I lazily stretch and begin checking the original Jacob's background. He has a trillionaire father and a billionaire mother. On top of that, he has seven rich and beautiful older sisters. With such a ridiculously overpowered setup, how can he go around simping for a broke college girl with no money? What a complete waste!

Tiara wakes up inside the comic’s story, in the body of the tragic heroine doomed to fail the one man who ever loved her: Luke Thorne, the immortal hockey star who hunts under the moon. She knows this story. Every twist. Every betrayal. Every heartbreak. But this time, she’s determined to rewrite the ending, to save Luke and maybe heal her own shattered heart.

Suzy was the only normal person in our family. While our father drank himself into oblivion, our mother gambled away everything, and I descended into mental illness, she sacrificed everything to pay our debts and keep us alive. She even found the best doctors to treat me. We all carried a lifetime of guilt for dragging her down. Then she became engaged to the heir of the most powerful family in the country. Only after I died in a psychiatric hospital did I uncover the horrifying truth. Suzy had been chosen by a system. My father's alcoholism, my mother's gambling addiction, and even my mental illness were never accidents. They had been carefully engineered to create the perfect tragic backstory for her, shaping her into the resilient, selfless heroine. We were nothing more than disposable tools in her mission, used until we had served our purpose and then discarded.
