Recs if you like Three Days of Happiness...

Tired of looking for something to read among novels that haven't even concluded yet? This list is for you. This list will mostly be Japanese [light] novels, since that's what I read, but other Asian novel suggestions are welcome, too. I will try to avoid machine "translated" novels. This list will include both fan and official releases. The only criteria is that the main series must be available to read in English in its entirety. Side/extra chapters don't count towards this criteria.

PB is missing a lot of series, so this will take a while...

Fictional stories centered around a small business (sometimes supernatural, sometimes not!) and the positive impacts it has on its patrons

Light Novels with a wide appeal for everyone and that also have fantastically memorable stories~
