I knew they wouldn't have sex before I even read the chapter. I do not possess any spoilers. Why I knew, was because the entire motivation for Asumi going to lesbian brothels in the first place, was to find and reconnect with Mai. Once the two of them have sex, Asumi has fulfilled her goal. When it comes to romance manga, including yuri, there are only two possible outcomes after the main character gets together with the person they love.
Option 1. The manga ends. If you're lucky, you'll get a very short epilogue. The vast majority of romance manga end this way. Really disappointing; and I hate it.
Option 2. The manga continues and we actually get to see the characters date. The ups and downs of their relationship. See them grow closer together. This is my preferred outcome. But it's a mythic rare.
I really hope we are going for option two. I worry that the author is planning on ending it as soon as Asumi and Mai have sex. So she'll just keep coming up with ways to delay it for a ridiculously long time. Don't get me wrong, there is stuff to be dealt with and I do want to see addressed. Mai has a rival for Asumi's affection, (friend with benefits), that she doesn't even know about. And will Asumi stop visiting lesbian brothels once her and Mai start dating? Lots of great potential there.
