Nobody talks about this one. Two episodes is all it takes, Ruru's memory of a single friendship fractures across time, and you watch the same conversation happen three different ways depending on what she's actually remembering. The show doesn't explain which version is true. It doesn't matter. What matters is that forgetting someone you loved, or being forgotten by them, leaves the same scar no matter which story actually happened. This hits because it knows the cruelest part of losing someone isn't the goodbye, it's not knowing if they remember you the way you remember them.
Artiswitch: Ruru's Episodes of Memories is a 2023 drama and psychological ONA from Sunrise.
