[Fantasy (there are ancient times and different worlds) + sad stories (there are also good endings) + short stories]
It's old (oh no, it was written so long ago that it has fallen into disrepair?), Ahem, the articles written before and before are indeed youth pain literature, so be careful!
The plot, uh, I forgot, it's probably something like a quick time travel. It can also be read as short stories. There's not much connection in the early stage, uh, maybe it's not that big in the later stage?
Anyway, in one sentence, early youth pain literature, enter with caution, enter with caution.
