In Zelda's diary she directly references hostility towards Link. She
conducts the stupid ceremony like a wake, questions Link's sword proficiency Link
calling him "...hero" as if he's undeserving, is a
raging ***** when Link has to do his job the king appointed, never is
shown or implied to thank Link for
rescuing her from the Yiga clan, she's manic and wants Link to
eat a frog .
She does
say Link's commitment is "admirable" but otherwise their interactions are just business and Link having to endure her martyrdom. She never expresses gratitude, ever.
Everyone else has to take care of her when she's frustrated and she has to be the center of attention, never asking how their day's going. She
says "save yourself" when there's no indication Link can run as he's already fatally wounded so that doesn't count; he doesn't get hit again but has to go to the shrine of resurrection after that. Frankly my dear, I don't give a damn.
It's a low level form of narcissism, my grandma was the same way; only her problems mattered and everyone was expected to drop their lives for her. The other champions and Link are the ones actually fighting Ganon.
