Honestly not sure. It was just my guess based on the interactions and dialogue so far. In all honesty, it feels like mangaka is setting up the scenario where she reprimands him for superimposing the previous priestess' image on her and that she's her own person.
Ancient Dragon-sama know in order to win Satsuki's heart he must first gain the approval of the people around her. Fastest way is always buy them off with high quality meals.
I know. I mean peoplr react normally when a dragon turns into a pretty boy, without "Oh no, here we go again". And it is pretty often, too. Veldora, Acno, Ignia, Haku, Mercphobia etc etc etc.
