Headscratchers / Isekai Quartet

• Kazuma states he's not interested in returning to his world. Tanya decides to put him through Training from Hell to motivate him. But earlier we saw Tanya she was happier being in this world than her own, so why does she care? Shouldn't she want to stay as well?
  • In Episode 3, she's happy to get a safe, quiet life that has nothing to do with the war, but the new world is so confusing and chaotic that she just can't relax.
