Hi i want to know if this Anime has some Manga after the 25 episode?

As far as I know, there is no Manga after the first few chapters. The entire series was based off of a novel, rather than the stereotypical manga. The official Manga came at a later date, based off of the novel, as well. The Manga itself jumped through the first few episodes, and a bit near where the first season ended, and that was it. So no, there is no other manga, as far as I know. However, there is the original novel that it's based on, but that is Mehr directly aimed towards the romances with each girl in the first season, I believe.
