Huh. I wonder if it really was an early retcon by the author because in earlier chapters it certainly seemed to be the case that she was part of the clove room.
It may be a misinterpretation in my translation, so I modified one part in chapter 10 and now she says:
"Recently he's always inside the clove room" "but, even though we live in the same castle, it's hard to spend time together"
Before, I omitted the castle part thinking she was inside the clove room with him..
So yeah I created that retcon D:
