Reverse isekai, where Kei who is a knight, had found himself in a modern city.

After losing his beloved lady in a ruthless power struggle for the throne, Kei's world shattered. Grief twisted into rage, and vengeance became his only purpose. For months, he hunted down those responsible, spilling blood in her name. But vengeance came at a price.

Surrounded by enemies, weakened and bleeding, Kei faced his death with defiant eyes. Their blades found his chest, stealing his breath. Pain burned through him, but there was solace in his final thought—he would finally reunite with her in the afterlife.

Yet as the shadows closed in, a figure emerged, standing before him. Kei’s fading vision sharpened with disbelief. His breath caught. It was her.

But how? His lady, the one who had died in his arms at the hands of her own brother... was standing before him, alive.
