I've been reading 'I'm Just a Villager, So What' without realising it was the same author vol. 2 just came out yesterday so I was literally reading it before and after this part - it's my favourite of the Hanashi ones.
This wrapped up better than I thought it would. Everything explained and we get a taste of how things are going forward - although at that point he could've just regained his memories - I do appreciate that the author is willing to leave affection unrequited, I don't have a problem with it, but 'harem ever afters' are getting a bit old; admittedly this is toeing that line, especially with the sister, but you can't say that's what happened.
