Art animation is good even though it's not my favorite genre. The truth is that Studio 9 Maiami created this H is also the same studio that created Discipline one of my childhood H. We can recognize the character art lines are quite similar between the two names. Personally, I really like the art of this studio. I am very impressed with Anime or Hentai with unique and strange art, such as this OVA. As for this OVA, since I'm not a fan of the NTR genre, I will say that I'm not very comfortable watching it, but I still enjoy it in a few ways,for the animation part, this H is made in a "manga style" in a few scenes, it was quite special so I noticed too. And actually the scene where the guys took turns taking Ayaka to buy things outside and then coming back and Hiroshi's expression really made me laugh. Perhaps this is the rare H-OVA that includes such humorous scenes. This is also the reason why I forget about the discomfort of watching the ntr genre. Yes, that part cracked me up. And if there's this Endou character in real life then he should definitely go see a doctor lol
