Koi Desu! is a blind girl meets yankee jdorama. It also has a very strong shojo manga style so that means it is extremely sweet and fluffy.
The yankees are not yankee like in the slightest which would not be a problem if Koi Desu! was funny. Unfortunately its not very I cannot stand how sweet and colourful the show is.
Of course I am not the target demographic so what I am saying is there is nothing else to watch Koi Desu! for besides the facts about blind people and how they go about their day (which I find interesting) and the blind girl's older sister which is the only slight comedy relief in this show.
If you like shojo mangas, this is the show for you but for everyone else, stay away!
