I fell asleep, missed my chance at happiness, and then the Demon Grand Duke appeared before me

One day, Charlotte, a college student, is reincarnated as the protagonist of a manga, and the young daughter of a marquis who happens to share her name. In the original story, when the heroine went to pray at the sanctuary, she met an angel there who granted her wish. Although she had been in love with Prince Isaac from the very beginning, she could never honestly express her feelings to him. However, thanks to the angel’s magic, the prince was able to hear the voice of her heart, and little by little, the two grew closer until they finally ended up together. But after being reincarnated, Charlotte accidentally oversleeps at the exact time the angel was supposed to appear, and the one who ends up hearing her wish is a demon. To make matters worse, Maynard, the demon, is furious because Charlotte mistakes him for an angel, so he twists her wish around: instead, he makes Charlotte able to hear Prince Isaac’s inner thoughts. And, as if that were not bad enough, Prince Isaac was nothing like he was in the original story, but rather an obsessive, cruel, calculating, and ruthless man. After discovering his true nature, Charlotte gradually begins to avoid him, but that only serves to spark Isaac’s interest in her even more, putting her in serious danger. And the one who comes to save her is none other than Maynard, the demon who lives in the same kingdom as a grand duke… though it seems he will not be easy to deal with either…
