“The Enchanting Beauty”

That was the epithet bestowed upon a single model.

A prince from a certain nation had proposed to her. A petroleum tycoon from another had done the same. Whispers of such rumors spread, all because of her breathtaking beauty. Sakakibara Tsubame—an extraordinary young woman—had once been the childhood friend of Yukitsuki Shigure.

Back in elementary school, Tsubame moved away, and the two gradually lost touch. Shigure resigned himself to the thought that they would never meet again.

However, on the day of their high school entrance ceremony, Shigure encountered Tsubame once more. But the girl who stood before him was no longer the one he remembered—her expression was vacant, and a deep, unfathomable darkness had taken root in her eyes.

And so, as Tsubame, now broken, sought solace in him, Shigure made a silent vow—

To bring her happiness, no matter what.
