I just feel like they'll both reborn in our era (as humans i mean) et will live happily ever after (=・ω・=) I picture myself their fatefull meating like in Your Name :D
I am sure that his brother isn't a villain. It must be more complicated than just him wanting to be the emperor. I'm sure he's using the villain organisation to trick them and protect the empire. I believe he loves his brother (like a brother i mean)
I had it racing this hole chapter omg I'm not feeling good AT ALL
