Much of the actual things that has happened in the ending of Sundome is left as an open intepretation for its readers. The sensuality of the last chapyers, although not as plenty as the previous ones, are definitely the most erotic the two protagonists has ever gone to. This is the ultimate blue balls manga, depriving Hideo Aiba of sex despite numerous extremely close encounters with Kurumi. 
 I enjoyed reading Sundome for what it is, forgiving the sheer amount of ridiculous elements Sundome is stuffed with and just going where the story brings me.
