Amai Ijiwaru

Once the divorce between her parents is finalized, Kotori's life narrows to just her and her father Naoto, and somewhere in that quiet domesticity, her feelings start crossing lines they shouldn't. She doesn't just want to keep house for him, but she wants to replace her mother entirely. Naoto knows something is shifting between them, and he's fighting his own internal battle to keep things where they should be. Then Kotori's friend Rina enters the picture, shy and seemingly harmless, but she stumbles into knowledge that gives her leverage over Naoto, and suddenly this already fragile household dynamic gets a lot more complicated. This is a 2025 OVA from Studio Nur, and it leans hard into the psychological tension side of things rather than just being straightforward about its genre. The character dynamics between the three leads actually have some weight to them: Kotori's desperation, Naoto's guilt, Rina's quiet manipulation. There's a real sense of moral unraveling happening beneath the surface. If you've watched Oni Chichi or Kanojo x Kanojo x Kanojo, you already know the territory, but Amai Ijiwaru puts more emphasis on the emotional conflict driving everyone's decisions. The animation quality helps sell the subtler expressions and body language that a story like this needs to land properly. It's not trying to be anything other than what it is, but it commits to the psychological messiness in a way that keeps things genuinely engaging rather than one-note.
