I’ve tried to avoid any spoilers until I finally have the time to sit down and properly play it myself. Tried playing it this spring with the Japanese audio and English subtitles for listening practice and I regret everything - it’s just so ridiculously high-paced that there was in fact no time to read the subtitles.

I had originally planned to extend the challenge to August but with daily Japanese studying and reading I kind of feel like I’m not giving myself a chance to actually relax and rest this summer. Plus I only have light novels/books left on my challenge list and those tire me out so much more faster than manga. So decided to just try and finish the 2 things I have on my list and take August easier.
July 13-14
First up was ふしぎ駄菓子屋 銭天堂 - read 19 pages.
July 15
Seeing the end of the challenge approaching I decided to take another look 夏目友人帳 and ended up reading 3 pages. I no longer look up everything and just try to understand as much as I can from context to speed up the reading.
July 16-18
Read the remaining 39 pages and finished ふしぎ駄菓子屋 銭天堂 1 .

I liked the ending of the ice cream story the most since it was so unexpcted.
Have you started on the second volume yet? @Aislin did mention the stories getting repetitive and I can totally see how, so I’m not 100% sold on buying the second volume yet.
