This is the most emotionally impactful fanfiction I've ever read. It's largely canon-compliant (the one exception, Hero being trans, doesn't bother me) and its length respects your time. I have read it four times now and it has only hit harder each subsequent time. It has made me cry, multiple times. I can't recommend this enough to any Omori fan. I don't expect it'll hit you as hard as it hit me the third or fourth time, but regardless, it's wonderful and emotional and you can finish it in about an hour.
