In the MCU/Marvel with the Omnitrix/Ultimatrix - Chapter 45: Read this if you so wish.

He had been the best assassin of all time in his world and when he was finally killed, a goddess took the opportunity to send his soul into the body of a boy in another world who was weak for now but who was destined to become the most powerful mage of this world.

This young boy was called Kevin and he decided to take his identity as he had kept his memories.

The only thing he had in common with him was that they were both orphans, but Kevin had a weak mind and a weak body, in short, everything he hated the most.

After successfully entering the Sun Sect as a mage, he managed to open the book Kevin had inherited from his parents and which he had been unable to open.

What was his surprise when he realized that this book had turned into a System that allowed him to level up like in the virtual reality games he used to play in his home world.

With the help of this System he will fufill his wish, he will become the most powerful humans of this world, not even shapeshifters or demons will be able to do anything to him.

Kevin turned his head towards him and seeing that he was still naked he said, looking away again : “Get dressed first, then we'll talk.”

Axel found some clothes that looked loose and put them on right away, he also took a pair of daggers whose blades were just a little shorter than his forearms, and he then approached Kevin and hugged him from behind.

Kevin let him doing whatever he wanted, even though one of his daggers was now very close to his throat, Axel said to him close to his ear : “ want to trust you Kevin, so give me a good reason to.”

Kevin then asked him : “What do you want to know ?”

Axel sighed, threatening Kevin with his own daggers won't do him any good, and he risked breaking the bond they were just making.

He then took a decision and planted the two daggers in the ground in front of them, he ran his hands under Kevin's sweater and circled his waist with them, pressing him more against him.

Kevin hadn't expected this turn of event and he felt his heartbeat quicken. Axel's hands were warm and he could feel his huge erection against him, one thing was sure, it was that he didn't let him indifferent.

This novel is also known as Daughter of the Male Protagonist

As luck would have it, Luo Shuyan unintentionally found out that she’s a character from a male protagonist novel, and she happened to be the only child of the male protagonist.

The male protagonist had intimate encounters with countless women. He rose from being one of the poorest to one of the richest in the entire kingdom. He was a man that was above all others.

Well known to all, his only weakness was his dear daughter, who had sadly passed away early on in life. Even the female protagonist, who was placed at the pinnacle of his heart, didn’t dare to mention the name of his daughter.

Luo Shuyan, who was destined to die early, was perplexed with the setting of the story.

Additionally, she found out an even more intriguing fact — The mother and son duo who lived next door to her was the heroine and son from the novel, “Child Prodigy: Story of a Delicate Mama Fleeing with Her Child”.

#A story where the male protagonist is my father. Plus, an unbelievably cliche side-story of my childhood best friend’s mother who ran away from home#

#A melting pot of stereotypical plot points between male-centered and female-centered novels#

#Sigh, what on earth is happening?#
