Seems like there's 10 chapters total here. If I had to guess, it seems like this series covers 3 couples in the same group of friends. Chapters 1-3 are about one couple, and then Chapter 4 (and presumably 5 and 6) are about another.
If trends hold with similar yuri stories, we'll also probably see a little bit of the future relationships of the other couples (either in the background or in a couple of panels like "Hey X and Y have been dating recently!").
Edit: Now that it is fully translated, we know that past chapter 3, every chapter is focused on other people with one exception (chapter 6).
