This is one of the best regression story (at least the starting line of a story) I've read. The reaction when she came back, her personality changing after going through hardships, her starting to realize the preciousness of money, crying when eating Takoyaki, it's all portrayed so well in both the writing and the art style.
@iblues Your arguments were false, if I'm reading this correctly her wealth comes from her father, which got into a scandal (?) and commited suicide, but she didn't just went homeless right away.
According to page 6 she tried to use her beauty to rely on rich men, only to find out that they only wanted her body, and discarded her when she grew older. The text suggests that she only got homeless during her early-mid 40s (p5 says she passed her 30s), which makes sense given the context, and the time she died was around her late 40s (p6 says she's near 50)
Edit: After reading a few chapters in, this manga turned out to be fairly mediocre. The author keeps recycling the same comedy skit using the "misunderstanding" cliché. I expected more from this with how it started out only to be disappointed.
