After Phos had turned into a gem-human I had some concept that may or may not be able to fit Ichikawa's writing :') though recently I have a finished the manga and a void was formed inside of me soo with no willing to let go of HnK for now I decided to maybe.. publicize my concepts? (Previous called: HnK: Aftermath Concept)

Subaru lay awake in his bed, waiting. He had done everything right. He had trained, learned, hardened himself into the king he needed to be - and still, it wasn't enough. In the end, every one of his wives fell. And Reinhard came for him again and again, ending his life each time. But the cycle shattered. Subaru opens his eyes not to an ending - but to a beginning. Earlier than he ever returned before. Earlier than his first arrival to this world. Old bonds. New faces. A chance to rewrite the story from the beginning. Can he finally save the lives he failed to protect? Can he finally find satisfaction in life - or is it already too late?
