I Returned to the Immortal’s Youth

That is more or less the description of 95% of the novels in this genre :))

Right, there is that. For me it wasn't the main issue though, and while it's hard to create original content these days, here it was pretty much copying familiar stories and scenarios for what's been popular the last 20 years or so for writing all of the tales (scenario arcs), which kinda makes sense if you look at it as a fanservice to the original writers/creators. And while I wasn't enjoying every one of those arcs, I was more upset about the 'fan service' to the (changing?) audience of this story, where the main plot line was increasingly interrupted and populated by ever more irrelevant female characters, which made me question the target group of this novel.

Is this good?

It's a good book, at least from the few chapters I have read. Keep it up author

I always find the human/werewolf books interesting.

Great story, it hook me from the start!
