I donโt read a lot of manga, so will probably not participate, but I have one series I can nominate because I loved it and it fits this perfectly, imo.
Itโs quite expensive, so Iโd wait for a sale.

Summary - English
A sweet shop tucked away in a town. This store, run by a bear and a salmon, is only open at night.
All they serve is hot tea and a sweet dish. Tonight, too, people who are tired and want to cry wander into this store.
The night they gave up on their dreams,
The night they think of their loved ones,
A night when you hate yourself.
-On those nights, itโs okay to shed a tear in this store.
In addition to 52 pages of newly illustrated stories from another point of view, unknown to the main characters, 11 recipes for sweets are included.
Reason(s) for nominating: I loved it and I think everyone should read it if they enjoy iyashikei.
