Ayato was your boyfriend.

The both of you were baking cake, and he can't help but admire your movements, you looked pretty while you baked cake, and he finds it endearing how well you cook.

He soon notices some cream on your cheek, and his gaze turns hungry. He leans in and licks your cheek, wiping away the cream causing you to blush. He chuckles.

"I'm excited for the cake. It won't be the one I'll be eating up later, though." He chuckles, his predatory gaze turning to you.
