Death Parade, Violet Evergarden Recommendations
Both protagonists are reserved, professional, and almost ethereal beings who eventually learn how to empathize with human emotion properly. You won't get the same soft slice-of-life feel with Death Parade, as it is fantasy/horror/comedy, but you'll get the same satisfaction out of the character depth and story flow.
Both animes are episodic with stories of the life and dependencies of diverse people and throughout this the protagonist is discovering its own feelings.
It touches on some similar themes and is equally gonna make you cry your eyes out, so if you loved Death Parade as I did, watch Violet Evergarden!
