The protagonist is reincarnated into an aristocratic setting as the daughter of a duke. There, she is betrothed to a handsome prince... who just so happens to also be a sexually deviant and obsessive prince that corrupts her with pleasure.

The protagonist, who has been reincarnated into Meriel, is not a fan of the novel, but she is confident that she knows more about it than anyone else.

After all, this is a novel that she wrote and posted online before she was reincarnated.

In the novel "Crazy With Envy and Love," the protagonist Meriel comes of age and moves to the royal castle to begin her education as a queen. Soon after she starts living there, Kreuz uses his magic to sneak into Meriel's room and casts a spell to keep her awake until morning, licking her pussy, observing her vagina, and teasing her clitoris. It's a full-on erotic novel. After Meriel finds out about his nighttime lewdness, he becomes unconcerned and has sex with her wherever he goes.
Unable to bear Kreuz's sexual demands, Meriel confides in Roni, the son of a duke, and becomes romantically involved with him. What will happen after their relationship is revealed to the obsessive, perverted Kreuz...?
