Well when im searching for things to read i usually exclude the harem genre in the search and also double check the tags and read the summary before reading it, so i kinda had my guard down when it passed all of those steps and got really super disappointed It isnt the first time a interesting power fantasy disappointed me this way but like 85 ish percent of the time it does filter out the harem ones that I dislike.
And I wouldn't mind the harem if they actually wrote the female characters with more substance, but 98% of the time writers get vary lazy with the female characters(pretty, sort of sad reason why she didn't fall/get attached to anyone else, some how is ok with being the thirteenth woman)
So like can you blame me for being disappointed

Ugh all the women characters are so interesting but the author just had to make the relationship sexual from their end
Istg it hurts my heart, and its some lazy writing in my opinion. They couldn't have gone any different route but decided to shoehorn them into "love interests"
