Going by rental girlfriend readers, it is possible for people to both hate and love a series. Or hate to love, or love to hate it.
Otherwise though, it could be simply what is the main character of the story. When the mc is strong, they enjoy seeing them triumph. If the mc is weak, they hate seeing them lose.
Obviously the golden boy is not iding and playing with fire by himself, but it is inevitable nonetheless since the yellow boy can't possibly run from the crown prince anyways. If the MC is not by his side, he will get converted in no time lol
