Well, it looks like a good ending. I didn't really read all the chapters though since it's too slow for me and I'm too bored. The time I knew the ending chapter of this manga had been there, I immediately did read it. It seems like this is a good romance-filled isekai slice of life manga, maybe I'll give it a shot to read all the chapters if I have a time.
And also, the page before the afterword says that the manga has been serialized for 25 years instead of 2.5 years, which was surprised me at first.
