Fearbonding

Fear has a flavor to Hinata, and most humans taste weak. Kosuke doesn't. He's the first genuinely terrifying thing the demon has come across in ages, which is less a warning sign than an invitation.

Hinata's plan is simple on paper: get close to Kosuke, feed on his fear, stay undetected. The catch is that Kosuke is deranged in ways that make "getting close" a two-way risk, and a demon hunting for terror can just as easily end up supplying it.

You play as Hinata working that plan from the inside, easing toward Kosuke a little at a time while trying not to tip him off. It's a visual novel built around that tension rather than open exploration, so the actual work is reading the room, choosing when to push and when to back off, and figuring out whether you're the one doing the taming.
