This manga is a collab, I think, since the art style is too clean and professional to be one of the authors. This particular update seems more like the foot focus art the main author creates. I expect since this got popular on Reddit years after the release, the author is trying to continue it alone.
It's like, softer and looser. Early chapters have fairly stationary poses, characters are either standing straight up or sitting. The lines are very straight as a result. This chapter is more loosey goosey and dynamic, like when the girl is walking away. That's a crazy dynamic pose with lots of bends and stuff. Totally different to the straight poses of early chapters.
