About the [System] not being very noticable - there are a lot of levels coming up after chapter 40, I mostly wanted to avoid info dumps in the first arc, but I do try to explain more in the chapters before chapter 60. Cheers for reading in any case!
This is a LitRPG in the same vein as The Wandering Inn, so all the Skills' secrets are meant to be uncovered by the characters themselves instead of a description from the [System], it's just a style choice really. Sorry it didn't meet your expectations.
I don't know which chapter you are on, but the 'side characters' will get plenty of chapters of their own, so the idea is more that despite Livia being the leader and frontfigure the other team-members are equally important.
It's sort of inspired by 'Arrogant Young Master Type 4 Template A' that just because Livia fits the box of protagonist and is a timetraveler etc. she isn't special because of that, and doesn't get extra attention from the narrative, instead her actions will do so in the future to earn her that status, like Erin in TWI
I am a very new writer so learning when I am being unclear is very important!
If you had specific questions about things you found confusing I would be happy to answer so you can better enjoy the story. But I totally understand if you already moved on to something better, I know I would!
