A very gentle full color manga with short (2-6 pages) vignettes about Shiori, Sanae, and Haruko, three older women sharing an apartment in modern-day Tokyo. There's no overarching plot for the most part - we know that Shiori is divorced and Haruko is widowed and that the three of them have known each other for a long time, but there's almost no backstory. This volume follows the women through the seasons as they enjoy the holidays, come up with ways to entertain each during the rainy season, and buck each other up after hard days at work.
I bought this in Japan last year and only got around to reading it today. I thought it was a one off, but the second volume is already out, with the third due in February.
