The knock was tentative and small, making Asta assume it was Saba, Ahran, or Hera, but when she peeked through the peephole, which was just an organic knot hole in the wood of door, it was, to her surprise, Prim.
Asta almost hesitated to open the door, not prepared at all to speak to her new sister, but knew it would be terribly impolite - also knowing Prim, she'd bust in anyway somehow. So, straightening up and patting down her nightgown that she hadn't bothered changing out of of, the doe opened the door, trying to plaster a smile on her weary face.
"Hello!" She said sweetly, not opening the door all the way, hoping that maybe Prim was just stopping to drop something off.
One look at the wolf's raised eyebrow when they locked eyes said that that wasn't what she was here for though, and Asta wasn't bold enough to block her entrance, quickly giving in and opening the door wider, allowing Prim to brush by her.
