It’s pretty interesting how I clicked the “Insane Amounts of title” tag and noticed that many yuri titles under it often involve themes of dubious consent or unique, unusual concepts. For example
- A Yuri Story About a Girl Who Insists "It's Impossible for Two Girls to Get Together" Completely Falling Within 100 Days
- How I Lose Bets With My Sadistic Gifted Childhood Friend and She Steals All of My Firsts
- A Yuri Story About How My Classmate Whose Only Good Trait Is Her Excessively Pretty Face Comes at Me Relentlessly
A Story About Buying a Classmate Once a Week ~ 5,000 Yen for an Excuse to Spend Time Together, has a distinct and unusual concepts, but I wouldn’t categorize it under dubious consent. Even without reading the light novel, I get the sense the story won't take the path of Dubious consent. ( haha... just a little observation of mine ;D)
(What I mean by "unusual" is that it has a unique feel but you can still compare and relate it to similar works. For example, I’d consider Black Lagoon unusual and unique, yet I can relate it to Jormungand due to their similar vibe, especially in depicting the underground business world.)
