>there are no lewd romantic moments in most chapters either
Other than the 3 we talked about, Bokura no Ai wa Kimochi Warui has lewd scenes almost every other chapter, 4/20 effective serializations is 20% which seems reasonable for a magazine that's trying to appeal to a diverse array of customers (from male to female fans)

>something needs to happen to call something a story
We have genres like CGDCT and Slice of Life which almost exclusively focus on the day-to-day activities of the cast.

>the magazine doesn't believe in just allowing stories to end after 12 chapters that should
Plently of series end after 1-3 volumes in the magazine. Pic-related is an example was announced to be one volume (and it had a kiss basically every chapter). That photopgrahy one is also a short series. Whether you feel that they're being dragged out or expanding on the characters is ultimately a subjective determination though. It's ultimately up to the artists if they want to keep going or wrap it up.
