Some clarification on chapter numbering:
We found what's currently labelled as 6.1 via twitter (iirc) and did it because it was cute.
Turns out there's a version of the series release on pixiv, where it's chapter 3. I just looked for the tankobon, and the tankobon reshuffles into "chapters" that contain "episodes." Each couple gets a chapter, and there are a few episodes in each. So I decided to use decimals to number it. if that's too confusing, someone let me know and I'll fix it.
P.S. If you want to help scanlate this series, drop me a PM
