Three manga is connected with each other.
1. Amato Amaro
2. Kuma to Interi
3. Aru to Neri to Sono Shuuhen
But maybe no. 1 can be read after all of that? But I read it like that and I knew the characters from Amaro and understand better. Lol.
The mangaka really have his/her unique style of art and sometimes, sure, I got confused but overall I like the story and I found it funny too. I like the cameramen, Neri, son of Gelato master, and of course the three best friend (really big '?' here) of costumers of Gelato itself~
