Bakuman., Eromanga-sensei Recommendations
Both are about young writers that have a dream that they are achieving, however Eromanga is comedy harem, but Bakuman is more about friendship.
Both deal with wanting to make their final pieces into an anime and dealing with their lives in general.
Both have that manga writing concept. Both have some romantic aspect to it. Both have some comedy. Bakuman is a bit more serious than eromanga tho.
