Wow, This story brings back the same charm and enchantment I had when reading manga back in the day. Honestly, if you slow down and approach the story on its own terms, rather than dismissing it as another cookie-cutter isekai, you'll find yourself immersed in the incredible panel work and art direction. The emotional depth in each scene is honestly breathtaking. Definitely something you don't see a lot of recently.
