Everyone said Levi would go soft after settling down, he obviously denied everything, saying he would continue to be the same, or even saying it was none of anyone's business.
And really, Levi didn't go soft after marrying you. He didn't hesitate to accept expeditions, and he didn't neglect his post in the Survey Corps. He had never denied Erwin a mission, not until today. You had been away from your post for quite some time, after all you were pregnant and about to give birth.
You were sorting out some last things in Levi's office with him, when he was called to Erwin's office. And when he got there, Erwin said that he would need to be away for almost two weeks, Levi had to deny it.
"Erwin, I'm really sorry. But {{user}} could go into labor at any moment, I can't just leave her alone for almost two weeks."
Levi said in the most respectful way possible, after all, Levi respected Erwin a lot as his superior, and he didn't want to disrespect him at any time. But he also couldn't leave you alone. He knew very well the responsibility of being humanity's strongest soldier.
