The picture is different from the middle of the page, but there is a reason for this: pages 1-10 were drawn by me in the early days, and pages 11 and onward were drawn a few years ago. When I first drew it, I ended it in such a way that I could imagine many things that would happen in the following years. But a few years later I wanted to draw what happened in the classroom.
I was going to translate only the illustrations after page 11, but that wouldn't have connected the story, so I included the illustrations from the early days, even though it's a little embarrassing. When I was translating, I looked back at the illustrations again and found that the story is still enjoyable, even though the illustrations are not so good. I guess my tastes are always the same.
Since there are more than 10 images this time, I've attached a zip file to save them.
