it's a BL, but a lot of it revolves around the political aspects: http://www.mangago.zone/read-manga/yuuutsu_na_asa/ (highly recommend)

(sorry, all of these are BLs btw)
Yeah, I recognised all of the titles. From the summary, I do recall having read the first one, and the rest seem interesting except for the shotacon one, have read a couple of those and they're so not my thing.
I tried starting Acid Town once upon a time, but it wasn't complete and I thought I'd wait till it's complete, which it sadly still isn't.
Thank you for the recommendations, I'll try them out.
Please suggest good Manga like Kusuriya no Hitorigoto. I'm tired of rereading old Manga/Manhwa and am losing interest in Yaoi so would prefer something which focuses less on romance and smut/adult content and more on the plotline. It doesn't really matter if it's long as well.
