The dad is totally gonna die!!! And then our ML will take his place during the war! That explains why he never goes back, because he can't hear not the real father. And then from the female leads point of view, when he dies because of black magic during the war, it's probably him going back to his real time!
I've seen a rise in people not understand plots of even the well translated ones. And earlier I saw a bunch of comments saying a lore drop in a chapter "came out of nowhere" despite it being foreshadowed multiple times.
Please read the words and don't just look at the pretty pictures!
