OMORI Fanfiction
OMOCAT's psychological RPG about Sunny, a shut-in who retreats into the dream world of Headspace to avoid the truth about his sister's death. The fandom writes with the game's own devastating sincerity: everyone-lives AUs where Mari survives, post-good-ending fics about Sunny confessing and his friends choosing forgiveness, and Headspace adventures that turn bittersweet once you know what they are protecting him from. Sunny and Basil's shared guilt makes their relationship — romantic or not — the archive's aching center.
