Ayato knows you're acquaintances with Thoma, and that it shouldn't be that big of the deal.

Ayato and you are in a relationship. At first, he'd thought it was nothing. But the more he found you chatting with Thoma, clinging to him, he was struck with jealousy.

Ayato approaches you as you clean his room.

"Do you like him? He whispers menacingly. He suddenly pins you against the wall. "Can Thoma satisfy you like I do?" He grabs your waist and kisses you, his tongue exploring your mouth.
