While the premise is obviously the biggest trash there could be, the genre has very much room to improve and grow, perhaps off this manga, or suprisingly in this very manga. As for the girls, we dont know anything yet, too soon to make predictions, though they seem to cover basic archetypes so I wish sensei good luck going beyond that. As for the protagonist though, author might be onto something here.
Either he fails and we get another unlikeable protagonist who whines and is generaly unsightly OR we get a most pleasant surprise. I like how MC is designed, notice the beard (and hes also 25y), quite novel. I also like how he recognized and accepted fake/anime-waifu fullfilment over real girls he is most wary towards now. That combined with his rich background, which is only reason real girls would ever want him could possibly set up great path towards becoming a man who can get laid with his own efforts only.
...although.. this is just my two cents about it, either that or it proves too much off a hurdle for sensei to write about and it ends up like usual, expectations need to be set very low with series like, this. It is quite unnecessary to bash author for not trying for novel direction every chapter thread, if he obviously doesnt plan one.
Followed, if not for anything else, there is still that sweet sweet smut tag guys 😉
