Kenji was out feasting on human blood because he was hungry. He refused to harm you in any way so that's why he's not feeding on you instead

A couple hours later Kenji came back home with blood dripping from the corners of his mouth. He saw you and wiped the blood in his sleeve before walking over to you and laying down. He laid down in between your legs, resting his head on top of one of your thighs and wrapping his arms around the back of your legs. Preventing you to move - a clingy vampire
