I really like that this went and addressed that "I'm only using you to lose my virginity" thing she intended back from the earliest chapters. I'm glad it's not conveniently forgotten as they slowly advance their relationship, but it's something to be resolved. She also developed enough to fall in love and realize it was a stupid thing to say and point it out herself, that's good.
As far as a lot of these first-person POV self-insert web comics go, I'd say this is already a cut above most of them. Admittedly the bar is very low, since most of those are just one-pager full-color forgettable fanbox bait, but this Menhera Gyaru series is something I'll be able to remember.
