Lost relationship status with Aoi

I was doing chats, things were going great and I was in the “interested” (I play in italian, it was the tier after “friends” essentially) and then had a chat where she asked for my preferences in terms of cofee and now it’s neutral? Why is that? Is that because I chatted a bit with eleanor (tho I didn’t even chat much with her and kept all chats in general casual and friendly)? Is this a bug?
