If you love kids, this anime is for you! You will definitely be overwhelmed by the cuteness of kids of the babysitters club.Every kid was cute, but Koutaro was the best.
Beside that you will like the positivity very much and especially the innocence of this anime, it is the main fact. The discipline and perfect mannerism of Ryuuichi is also another good part.
The friendship, a completely different view of the school life are some of the unique parts of it. There are also a lot of other things but you have to watch it to learn those!
