I thought the character development was decent because there's obvious change and the author incorporated scenarios that would highlight that development which was nice. Overall, it was a good manga to read if you're looking for something easy and light that packs cute scenes, emotions, and good ol' camaraderie/rivalries. One thing I thought this manga did a good job at was actually showing what the leads liked about one another; it was clear and it seemed more thought-out than other mangas I've seen. But I had pretty serious second-lead syndrome with this one as well... I hope you enjoy reading this if you choose todo so!
