one can argue that it isnt a harem.. rather it's more a failed harem, he tried to create one however only 2 have some romantic interest in him and one is more of a sex buddy, of the 2 romantic interests one is almost abandoned (or extremely slow) thus only leaving with only one love remaining. thus in my opinion it's not enough for a harem tag.
I just realized something as I looked over the current top all-time viewed series on the site. You are the only OG poster on the site who is still making a regular strong showing on the trending ranking.
By OG, I mean back in the early days (Of only a few months ago, lol. Yay internet time.) where all the big stories were stories that had transferred over from Royal Road or other such sites.
Kinda interested in your story but curious about one thing so i can prepare my heart : how does romance works if MC is a god ? Will the FL(s) die of old age or something ? *Realize something* Ah ! Don't tell me MC will make them immortal or something ?
From the beginning, the main cast of the story are all immortal. They are entities created through the Keeper's system to help guide him over the course of his time as Keeper. This includes both male and female characters(though admittedly, far more female characters as the Keeper initially planned to make a harem when he wasn't taking everything seriously yet).
