The "heartless man" traveled through time and transformed into a dog.
What tragic fate awaits him?
The author doesn't think too much when writing a short story, and he doesn't avoid anything. He just wants to use his own imagination to write it and enjoy it. If it's a short story, it won't be standard. You can read it yourself. Anyway, the text is so short, there are not many chances to surprise everyone.
