Here be my scan of the single greatest doujinshi ever made. I have never been able to find a high resolution scan of this work, in Japanese or in English, outside of the original monochrome release.
Brief note on the structure: "Chirei de" comes in three parts. Part 1 was originally released as a standalone black-and-white book, then when time came to release part 2, Karaage Tarou seemingly went back and re-colored part 1, and released both parts as a single book. This is what this book is. Jou (上) and Chuu (中) mean "Top" and "Middle", respectively, which is a common Japanese way to describe trilogies (top, middle, bottom, in that order).
Then, part 3 was released already in full color, as a standalone book that's bigger than parts 1 and 2 combined. So while it technically consists of three parts, to get the full story in full color, you only have two books to buy/get/rip/scan/conjure/whatever. There's also a supplementary artbook, あのこがしんぱい (I'm Worried About Her) which is lovely, but that I probably won't bother scanning because it is surprisingly expensive and hard to get for such a tiny thing.
Translations: Part 1: /g/517411/df3dfcfae9/ Part 2: Oddly missing, but you can go to Danbooru or Dynasty Walker or MangaDex or any other site to find it. Part 3: /g/600369/8e3abf82b6/
As 癒し as it gets. I would have liked it more if they had focused less on the pets, and more on Koishi and Satori and their feelings and situation, though.
