Okay, that book is actually extremely good. it starts as if it was an Isekai but quickly, we understand that there is soooo much to discover ! the writing style is too interesting cuz we can feel the character's feelings. as if we were there. the story isn't surcharged with useless details or description. but the chapters are a bit long in the beginining but really entertaining. the character's are attaching too and the story has mysteries and let us feel like everything is connected. i just wanna know WHAT THE HELL HAPPENED IN THE PAST !! Please, update chapters more often
