Roy’s life was nothing special. The only thing commendable was the last few moments when he saved a mother and her child from a drunk driver.
…
It’s really an egg! Damn it, what kind of monster have I become? Did I fall into Hell instead of making it to Heaven??

The Soaring Dragon Continent is a world of summons, you can only become strong if you become a summoner! Yue Yang, an average high school boy, was suddenly transported into this world. When he woke up, he was greeted with a lot of worried faces and found out that he had assumed another person’s identity. Turns out he’s the good-for-nothing third son of the Yue Family, who had just recently drowned himself because of a failed engagement. Unlike the third son of the Yue Family who was useless in summoning, Yue Yang succeeded in making a contract with a summoning grimoire on his first try, even when the other guy failed for the past fifteen years. Others would have a headache making contracts with beasts afterwards, but countless beasts tried to gain favour with Yue Yang instead, acting like a good kid before him.

There was a popular comic that captured the hearts of readers not because of its plot, but rather the bromance between the two protagonists, a crown prince and a duke. Their friendship & mutual trust led fans to ship them endlessly, with countless fanfiction stories ranging from dating to marriage or even incorporating omegaverse settings.One particular m-preg fanfic novel became extremely popular among fans, where the previously cold duke becomes pregnant.But the popularity of both the original comic and this novel caused everything to become unbalanced, until something strange happened - these works of fiction turn into real worlds that collided, creating an error that connected them together.In the world of the comic:Carlton from the fanfic world gazed up at his husband with longing eyes. “Husband...” He pouted, “Why don't you kiss me today?”Alaric from the comic world recoiled slightly and goosebumps broke out over his skin as he moved away. “Please don't come close to me...” He said tersely.Meanwhile, in another world:Alaric from the fanfic world, pulled his beloved Carlton into a warm embrace and peppered kisses on his cheeks. “Darling, are you mad at me?” Alaric asked affectionately. “It's okay, you're still cute.” He leaned down to whisper into his ear before continuing. “But don't forget to comfort all our children, they think you're mad at them.”Suddenly, seven children barged into the room and called out to their fathers. “Father, Daddy!” they exclaimed.Carlton's frozen expression spoke volumes about his state of mind as he tried to process what was happening. His murderous gaze fixed on Alaric as he muttered through gritted teeth. “Whose children do you say they are....?”
