... I get it, and I don't at the same time.
I can understand wanting to go back to "your family", and "your world". It's actually kind of disturbing how easily the average isekai protagonist just forgets about wanting to go back.
But, and let me emphasize she died. And she remembers having died. What family is expecting her to go back? And if she goes back as a baby, does she really think her family will go "Oh, our daughter/sister died, but she came back as a European baby"??
