There are a lot of manga where the characters don't age at all. Sometimes the manga could be publishing for years, and the characters are still the same age they were when the manga began.
Then there are manga where character age progression is done through cop-out methods. Sometimes it's a timeskip, where everybody's suddenly older in the next chapter. Other times, it's through an epilogue at the final chapter.
The above two are things that I am not looking for.
I'm looking for something where characters do age, but it's done slowly over the course of the manga's publishing. So the characters should see gradual changes in their lives, but it doesn't hit them head-on.
An example I can think of is Kimi no Iru Machi.
Spoiler (mouse over to view)
The characters start in high school, then they move up grades, go to university, get jobs, and start families.
The story isn't directly about them aging, but it's something that happens to be included.As for genre, it doesn't matter too much, although I think Slice of Life would suit my request quite well.
