Doujin Work, Eromanga-sensei Recommendations
Both are similar in their depiction of a group of friends that is involved in the creation of manga/ln.
'Douijin work' is more concerned with the details of the doujin market and the expectations of its fans. 'Eromanga-sensei' is more concerned about the relationship of the main protagonists.
Both feel similar in that they are taking a lighthearted and relaxed approach towards the environment of ln/manga creation and and in their reliance on comedic interactions between characters.
