This show takes ‘show not tell’ quite literally, so it helps to pay attention in the episodes, like the dates for example. Not saying it’s that deep, but there a lot of hidden symbolism in images, as well as hints in text to tell you things that are happening. It’s a slow anime too, in terms of pacing as it focuses more on story and character rather than action. But once it picks up, it picks up. Also, there are extra scenes in the post credit of each episode; nothing that spoils, but more of an interlude before the next episode. But glad you enjoyed the first episode. It’ll definitely be a rollercoaster, and always happy to see more people seeing the anime.
