It was a long road, but it was a really nice ride, despite some bumps here and there, because in some sort of way, all the characters are lovable, and you really wanted to know what was going to happen to (most of) them!
I really wish Shimura would have expanded the series a little more in the sense of completing some plots between some of these characters better than making them fall a bit short. But, knowing that the series had also a bumpy publishing road, I suppose it was for the better. Graduation is always a nice way to end a story like this, but I guess I wanted something more after it.
This guide was quite helpful, so many thanks for that, as well.
