"Temporary relocation from a 'dilapidated apartment' to another world. What have you lost?"

"Would you like to become younger and temporarily move to another world?" "YES" A thirty-year-old office lady exhausted by her daily life carelessly replied to a strange email. From there began her temporary relocation to another world, and the things she discovered within it. A story until she finds happiness. I am posting a curveball version of this story (another world → the Land of Eternal Worlds) (increased number of characters) (increased word count from 1000 → 10000) on Alphapolis――――or rather, I am submitting it.
