Reader's Discretion Advised

It took a long time for me to figure out what was going on. All of the esoteric terms and whatnot. However, I did eventually kind of figure it out.I kind of would have liked to learn more of the implications of the ending, so sequel?I mean, as a romance, it's not bad, but I feel like this post-apocalyptic universe has merit and can/should be explored a lot more.If there's a sequel and it follows the romantic development of any permutation of other characters, I would scream because that is a stupid cop-out for the universe.And besides. The MC have a looong way to go. (I guess it's confusing that I sometimes use MC as "main character" and sometimes as "main couple"... Can't use OC for "official couple" cuz that's "original character" *sigh. First World problems...)Honestly, it's possible that I might have been more enamored with the universe than of the main couple and their "budding romance"...I really wanted the dude who bottomed to top...
