It's a very lighthearted manga, it's very enjoyable since it doesn't really have a complex storyline. It does portray the characters in a very amiable way, and no one should expect to really learn anything, I mean some facts are correct, like Beethoven being deaf (though not from a very young age, as they represent here), or the fact that the composer Rentarou Taki did die a year after he returned from Austria of tuberculosis. Overall its a very light read if you enjoy reverse harem, though it doesn't really focus on the romance aspect as much, it's more similar to those of friends, kind of like Ouran High School Host Club, though without so much plot.
