Doki Doki Literature Club began in 2017 as a free visual novel from Team Salvato that first looks like a light-hearted school poetry club story before turning into psychological horror. That contrast became its signature, and short clips from the game spread widely through YouTube edits, TikTok videos and soundboards, where fans reused them to signal a sudden tonal shift. The game remains popular years later because that mix of cute presentation and dark surprise is easy to reference in a few seconds, even for viewers who have never played it.
