I was reincarnated into an incredible world. Reincarnating into another world/summoned things are popular these days. I understand this because I've read numerous works. I have been reincarnated as Meriel, the main character of the novel "Crazy with Envy''.
Meriel is the daughter of a duke and the fiancée of Kreutz, the first prince. Kreutz is a good-looking guy with good manners, and what's more, he's an excellent magician.

However, he is unusually attached to Meriel.

The main character who was reincarnated as Meriel is not a fan of this novel, but she is confident that she knows more about it than anyone else.

Yes, this is a novel that she wrote and posted on the internet before her reincarnation.

In the novel "Crazy with Envy", after the main character Meriel reaches adulthood, she begins to live in the royal castle to begin her education as a queen, and as soon as her life in the royal castle begins, Kreutz uses his special magic to invade Meriel's room. This is a novel full of erotica, where Kreutz casts a spell so that she won't wake up until morning, licks her pussy every night, observes her vagina, and tortures her clitoris. After Meriel finds out about his mischief that night, he opens up and starts having sex with her anywhere. Unable to bear Kreutz's sexual demands, Meriel consults her childhood friend Roni, the son of a duke, and they become romantically involved, but their relationship is revealed to Kreutz, and in the end Roni is detained. Meriel is raped by Kreutz in front of his eyes and falls into pleasure.

She says, "The pleasurable ending is something she can enjoy because it's a creation, and she definitely doesn't want to end up in it.'' However, Kreutz demands her intensely, and she is at the mercy of his unimaginable pleasure. Moreover, it seems that the relationship with Roni is already deeper than I expected...?
