So, to summarize, this story goes around the life of several students at this upper-class academy and their romantic lives among them. It maintains a consistent light-hearted tone throughout each arc, usually consisting of a repeating formula: two characters meet each other, one falls in love while the other is hesitant, there is some petty conflict involved, they resolve the conflict, and then they kiss and are happy forever. It is pretty much the formula for generic happy romance stories; the kind someone would write when they don't have anything relevant to say.
Because of the fact that the author sticks to the same trope, most character interactions feel hollow; just streams of moeness aimed at the sensibilities of lonely otakus who don't get tired of drawn girls blushing for 50 chapters. The love chemistry is not fleshed out beyond a character blushing or having a excrutiatingly long backstory with her partner (say, being a childhood friend or an aunt); as a result, the personalities feel empty. But the even worse part might be the conflicts, which due to their pettiness can hardly come off as anything but ridiculous. A girl is mad because her crush didn't remember her from 10 YEARS AGO. Another one is mad because her crush (which is also her aunt, yikes) quit playing piano due to work WHEN DUH, THAT'S SOMETHING ADULTS DO.
Not a single one of the conflicts touches the personal; the gritty, the essential in a relationship. They are all like cheap fables; like children stories you tell to 11 year old kids who want to hear the "and they were happy ever after" part repeated over and over again ad nauseam. That, combined with the pretentious storytelling that tries to convey the complex romantic implications of, uh, realizing being good at everything doesn't give you a right to be an asshole —nothing is more annoying than a Mary Sue that is also self-centered like Kurosawa— with the most sappy and cheesy prose, makes this story a collection of boredom and mediocrity.
