You realize that with these kind of stories, if you do not throw a wrench into the status quo nothing would change, right? This is how many gag-love mangas have been born and stuck in an endless cycle of "No progress," and when they do get some, is rushed or completely out of nowhere for no reason.
Now, if you wanted this to become an infinite "Hino does lewds > Koguma gets angry > Hino lewds her more > Koguma agrees to Lewd but under a condition > Lewd happens > Hino-san no Baka! > The end." Then be sad, the author does NOT want that, he actually is making progress albeit small, and for that purpose, breaking the status quo is a must.
