Rumbling Hearts was an Anime missed by exactly who'd like it most.

Rumbling Hearts is an Anime that is underappreciated partly because it was missed by a lot of the very people it would most appeal to.

First of all it's mostly an Adult Life Drama but the first two episodes are in High School for the backstory.  So the people who want more adulthood in Anime should really check it out.

It also functionally has a very Shoujo or even Josei appeal but still gets officially classified as Seinen being a Visual Novel adaptation.

The show is an emotionally dense Melodrama where all the characters make bad decisions for bad reasons but you always understand them.  Something that takes really skilled writing to pull off.
