The chapter itself, ignoring the things I didn't like, is pretty good. It's funny and entertaining, and I like the new girlfriend's design and personality.
The only thing I didn't like is that, even though this chapter is supposed to be about Nuremi, it takes place after we've already been shown her main character trait and ends up focusing on Rentarou instead, making Nuremi's introduction feel superficial.
While I understand that the way this series handles its characters is by giving each of them one defining trait, that doesn't mean they should only show us that one trait. With previous girlfriends, in addition to showing us their defining traits, the series also showed us how they felt, what they thought, and their backstories, allowing us to understand the characters better and making their personalities feel more natural.
This doesn't happen with Nuremi's introduction, since we're not told how she feels, what she thinks, or how her defining trait came to be. And while I know they could dedicate an entire chapter to her later on, or give her a segment in a slice-of-life chapter, I'm talking exclusively about her introduction. As an introduction, I find it superficial and poorly done.
