@Seraphim Sorry to say, but it's finished :( "The End" is just not translated and it's also mentioned in chapter 10.5 that it has only 10 chapters.
It's one of these short stories.
Edit: I'm so happy I was wrong XD I was sure ch. 10 was the last one. I feel like I finally got the parcel I'd ordered ages ago and totally forgot about it until now.
