My sister Remia was the Crown Prince's fiancée.

However, because the Crown Prince had a child with another sister, Remia was forced to annul her engagement. And Remia, who continued to refuse the annulment, was poisoned to death by her parents today. Why did Remia, after ten years of effort, have to be killed? Unable to accept this, I decided to return to the past using a forbidden spell.

A story about an elder brother seeking revenge on the family members who drove his sister Remia to her death.

A common regression story.

I had an irresistible urge to write a regression story, so I wrote it all at once. It was intended as a short story, but it grew longer. I will divide it into parts, but upload them all at once.

As there are cruel depictions, those sensitive to such content should exercise caution.

Thank you for the many typo reports. I received wonderful reviews, thank you. Also, thank you for all the feedback.
