[ A tsundere to the end. Honestly if he was really wasn't a softie at heart and truly relished in being a rude meanie, he probably would have spent more time actually being mean rather than explaining to her why he really is not a softie at all.

It's like watching someone constantly claim they hate chocolate, only to find them stuffing their face with chocolate all the time! ]

I understand doctor. I will do my best to keep pretending you really are a heartless and cruel villain.

[ His secret is safe with her. Maybe.

That's unfortunate, he's probably permanently lost any hope of ever being intimidating or scary with Ereshkigal. Now that she's truly seen what his heart is like, there's no going back. But she'll do her best to spare him any further embarassment. ]

Please take care until then.
