【Manga adaptation serialization starts October 18th on Niconico Manga and Piccoma!】

The Duke's daughter, Claire, has her engagement to the Crown Prince annulled, and is then executed by her own younger brother.

All of this was because the Crown Prince's affection had been stolen by a commoner Saintess, leading Claire to go mad with jealousy and relentlessly torment the Saintess, ultimately attempting to kill her.

Claire died, regretting her actions. ...Or so she thought. But when she awoke, she was back to being 12 years old...?

If she could start over, this time she would live humbly and discreetly. She wouldn't cling to the status of Crown Prince's fiancée and was even prepared to hand everything over to the Saintess. So, she didn't want to die...!

Living in the same mansion was her younger brother, Phil, one year her junior. He and Claire, who was not related by blood, had been estranged. Five years later, he would fall in love with the Saintess and kill Claire. But, at least for now, he was just an innocent, adorable boy.

"Phil, you can be happy with the Saintess. So... please... please don't kill me!"

Claire dotes on her brother endlessly, trying to curry favor. She believes that by doing so, she can avoid her ruinous future.

However, contrary to her expectations, Phil becomes incredibly attached to Claire... And Claire, too, gradually finds her brother adorable, and begins to dote on him wholeheartedly.
