Also, a question, when are your wings supposed to grow? Restarted just to see if there was anything new, and to refresh my memory on things. Stuck at the mountain as they haven't grown yet, so I can't get the 5th Journal entry. Almost lv20 now, and I swear they grew before this last time I played, idk if my game is just bugged or what.
Edit: Decided to get Yuki while trying to figure it out and it auto removed her collar and auto selected her dress as well. Got home with her, had the whole conversation about the collar, then bam nothing further to do, auto selected the purple dress.
Edit 2: I did eventually get it, though it didn't give me a notification I had wings, just went back to the mountains and tried that path again and it let me. So, idk what's going on with it.
