I'm on a roll!
So, this one, abridged as Uta Koi because we're all lazy, is, well, maybe not a story, this episode adapted 2 poems of the Collection. It's basically a series about love stories, or so I understood.
Exactly as they said in the series most of us are going to be familiar with the Hundred Poems through karuta because we've watched Chihayafuru. For those who are not the series offers a quick explanations, that is something I loved about it.
The two stories it adapted were pretty sweet and seemed to be really close to the poems they were supposed to adapt and we got to hear it actually included in the story, that was great too.
And damn were the stories cute, I got really invested at some points, it was that adorable.
And it had good seiyuu.
Another one I'll definitely follow. You should too if you liked Genji Monogatari or even if you want to know more about the Heian period, it seems like a nice introduction to it and the anime actually explains things
