This is the problem of idolizing someone. Inevitably people will create a perfect image of their idol, to the point you can no longer see the mistakes and shortcomings in that person, later on, we subconsciously put our ideals, hopes, and aspirations in them, until...the idol makes mistakes even if only a little, it's enough to destroy the whole image you got about your idol as a consequence you begin to question your judgment then you become disappointed with yourself.
Disappointment turned to anger and then to hatred. Soon you find yourself hating your idols as much as you loved them before. This is why Lory never felt happy to be idolized by anyone, as if her burden is not hard enough she must worry she would disappoint other people she doesn't know.
