Zephyrus wasn't quite sure what Iris meant, although the first thing that came into mind was to apologize. But wasn't that something he was doing just a couple of minutes beforehand? However, a nagging voice in the back of his mind told him that he didn't really say the words "I'm sorry". It was more like he was trying to get around it, and maybe that wasn't enough for Iris.
She really had to be something in order for Zephyrus to let down all his walls, and she was someone special. Special enough for him to marry her and also to release her hands and his hold on her in order to kneel down in front of her. It was a little bit extreme, although he was definitely going for showing her that he really meant what he said. And it was going to start off with him on his knees, saying sorry. But not without him sighing again at the idea.
"I'm sorry. For leaving you, for leaving behind a sorry excuse of a note to explain it all. And as for amends, if it makes you happy, I..I don't know, I'll do whatever you want. Even if I might not like it, I'll do it."
