Missed My Happy Ending, Met the Demon Grand Duke

One day, a college student named Charlotte suddenly reincarnates as Charlotte, the heroine of a manga and the daughter of a marquis.

In the original story, the heroine visits a cathedral to pray, where she meets an angel who grants her wish. Although she has long been in love with Prince Isaac, she cannot bring herself to confess. With the angel’s magic, the prince becomes able to hear her inner thoughts, and through that, the two gradually grow closer and eventually fall in love.

However, after reincarnating, Charlotte accidentally oversleeps at the exact time the angel was supposed to appear, and instead ends up making her wish in front of a demon.

To make matters worse, the demon Maynard, angered after being mistaken for an angel, twists her wish and makes it so Charlotte can hear Prince Isaac’s inner thoughts instead.

But the worst part is that Prince Isaac is nothing like the original story, he’s actually a scheming, cruel yandere.

After discovering Isaac’s true nature, Charlotte begins trying to avoid him, but that only sparks his obsession with her even more, putting her in serious danger.

Just when Charlotte finds herself cornered, the one who comes to her aid is none other than Maynard, the demon who lives in the same country as a Grand Duke. But dealing with him may prove just as troublesome…!
