It's a somber moment, but part of him can't help but find the angle and the position...hopelessly adorable. Sweet. His hand rests against Levi's back once more, rubbing in gentle circles as he makes a soft, contemplative noise.

"Mm...I understand." It does hurt, to have made all these plans, only to not be able to see them through together. Of course it does...when that had been stolen from them once before already, too. Erwin can understand Levi's hesitation - maybe it would just exacerbate that sense of loss...but that's never stopped him from moving forward before.

"However, I think you are correct - they wouldn't want you to hold back, not when you've already made the effort with them, to find a place you both want. Of course we'll bring all of their things and keep a space for them, and hope that they return to us. I know it isn't what you hoped for, but neither of us would want you to hold back from something that you've wanted just because we are gone."

Even though it is so, so rare for Levi to express his own wants and wishes, things he desires for himself, there's no need for that now. Not here, when comfort, at least, is so unthinkably easy to attain. After everything he's been through, the very least Levi deserves is a nice and comfortable home. Sure, the apartments are decent enough, but if he can have better, then why not?
