【Story】
Akeboshi Yume suffers from a rare memory disorder caused by a past accident. It’s anterograde amnesia—memories fade away after just one day.
Yume has developed a habit of writing important commitments and fleeting emotions in a notebook to barely manage her daily life. She lives happily with her boyfriend Taguchi Jun and Himeta Nozomi, a handsome senior from her club.
One day, after eating lunch with her boyfriend, Yume returns to the classroom where the senior is waiting. The senior claims to have left something at Yume’s house and asks her to retrieve it. Yume agrees without hesitation.
When the senior enters Yume’s room, her consciousness fades. When she awakens, Yume is already having sex with her senior—the beginning of her descent into carnal pleasure.

Editorial Review
This work occupies the psychological exploitation subset of NTR—a niche that’s gained traction as creators push beyond simple infidelity into more elaborate coercion frameworks. The memory loss premise isn’t merely narrative window-dressing; it’s the operational engine that justifies the power dynamic and enables the systematic corruption arc the synopsis foregrounds.
What distinguishes this from standard school-setting NTR is the deliberate cognitive disability as predatory advantage. The futanari element combined with yuri framing positions this as a same-sex violation fantasy rather than the heterosexual triangle most NTR doujinshi rely on. That pairing is relatively uncommon—most futanari works either avoid NTR framing entirely or use it as incidental setup rather than central theme. The progression described (pure protagonist → gradually addicted) suggests a corruption narrative structured around the protagonist’s accelerating complicity, with her notebook serving as a tragic record of her own erasure.
The inclusion of a boyfriend creates structural tension: he exists outside Yume’s working memory each day, which means he cannot protect or even recognize the ongoing violation. This amplifies the isolation dynamic that makes NTR psychologically potent. The handsome senior’s exploitation of anterograde amnesia as a mechanism for repeated assault without consequence taps into a specific anxious fantasy about vulnerability and systematic manipulation.
The black hair tag and schoolgirl setting are mostly aesthetic markers here, but they anchor the purity-to-corruption trajectory the work emphasizes. Production quality and art execution matter significantly for works this conceptually dependent on visual degradation markers.
This targets readers seeking psychologically elaborate NTR with sci-fi-adjacent premise mechanics and same-sex dynamics. The memory loss angle elevates it beyond generic school corruption scenarios, though execution determines whether it lands as compelling character study or exploitative window-dressing.
A conceptually ambitious entry in psychological NTR that justifies its premise rather than treating it as afterthought.
