I canít really remember cause I notice that there are more to the story in the Manga in which the Anime left out. Example Ch. 9 is the Hotsprings trip thatís equal too episode 9 but the anime left out some of the stuff that happen in ch 8.
Although the anime (in my opinion) stayed true to the manga, it was not able to be as detailed as the manga.
Sorry if this is not much help, but I would suggest just scheming through the chapters that are similar to the anime. That way you donít miss any of the extra part that were left out of the anime.
