Violet Evergarden 3-5
Violet learns more about emotions by going to school, partying with a co-worker, and helping a princess.
I think the one-off characters are well developed, often more than much of Violet's co-workers at Lt. Col DIO's postal company. It makes sense given the premise of the show and isn't a bad thing, but right now I feel like I know less about that blonde dude who delivers letters than I do Violet's friend from school whose brother is a drunk. Overall it's been good to watch and I'd recommend it if you're looking for an anime that isn't about fighting and can deal with a very alienated teenage girl stumble through social interactions.
