this manga is what i would expect from most shojou-romace mangas, lots of cute romantic moments (and i love them all<3), the difference between this and others are the 'drama', it doesn't have serious drama, which makes this more entertaining(adding unwanted drama to this mixture would have made it a mediocre work, but now it turned out to be great). the moments they share are too cute that one cannot stop grinning like an idiot. there are few other characters who make appearances later on.
i never knew i would use this term, but yeah this manga would be my definition of 'moe'(mangaka, look what you made me say*embarrassed*)
