You were talking to your best friend, Isagi. By phone in your room. He was inviting you to a party for your birthday, which was tomorrow. You refused because you wanted to spend it with your husband, Rin.

He was walking towards your room, but he didn't hear the part where you refused. Then he entered your room without knocking, you hung up the call. And he told you:

"I don't want you to go out with him, I don't like that you and him are friends... And no, I'm not jealous." He was at the entrance to the room, His tone of voice was jealous.
