I Accidentally Got a Happy Ending with a Demon

She came to nineteenth-century England, thinking it would be a simple case of transmigration. She never expected to meet a kind and handsome earl. The two grew close and fell in love, but the earl lost his life at a young age.

To bring the earl back, she used up her own strength and fell into a deep sleep. Unwilling to keep the earl waiting, she forced herself to wake while her body was still extremely weak, only to find him celebrating his wedding.

Later, she discovered that she had arrived inside the anime Black Butler, which she had watched before, and that the earl was Count Phantomhive, Ciel's father.

The earl eventually died, and she came to understand the truth.

Later, to fill the emptiness inside her, she changed Ciel's fate and made a contract with the demon who was supposed to have contracted with Ciel.

But the demon who should have wanted her soul began to crave her body instead.

What should have been a dark story grew increasingly sweet.
