Kanojo ga Yatsu ni Idakareta Hi is your run of the mill blackmail/NTR hentai where a married office lady is blackmailed into an NTR relationship with one of her subordinates. A two episode OVA at 25 minutes each that aired in 2020. This is an original that did not take it’s source material from something else. But nothing alive is an original anyways.
The story for Kanojo ga Yatsu ni Idakareta Hi is painfully executed in some of the worst ways you can in any sort of film. Starting off the first episode with paragraph after paragraph of backstory which the viewer has to read in order to understand the characters and situation is pathetically bad. No one wants to spend the first 5 or so minutes just reading blacks of text, the point of an animation is to visually show us not to bore us to death with mundane details. Then after reading for the first quarter of the hentai we get just a really bland and uninteresting NTR story you’ve seen a million times making the text even more pointless.
The art is okay and the girl looks pretty good, but that’s all you can really say for the art. It’s just mediocre quality with decent animation, nothing to get excited about or terrible enough to warn you of the blandness.
The sound is kind of the expected, piano background music to try and give this a more dark tone, but the quality like, everything else, is sub-par.
