Supreme Dad: I’ve Returned to Spoil My Daughter

I call the protagonist Supreme every day. I don't understand. Do mortals have limited cognition? They are not of the same dimension. They are all called Supreme. Do you think that Supreme is just a name and come to deal with the Supreme? Then the official is worried about the Supreme every day. I feel that the protagonist is usually too low-key, too holy, and too boring, because everyone thinks that the protagonist is weak. The so-called Supreme is just strong, but not much better than a low-level monk. The supporting characters in the whole book think so.
