honestly a child having a crush on an adult does happen in real life but the part where they grow up to get together with the adult who only ever thought of themselves as the child's parent figure, or the adult exploiting the child's feelings for their own selfish reasons (although also common in real life) is weird and wrong.
if the childhood crush doesn't provide crucial backstory, trauma or moves the story forward, i find it strange that the child ends up being with their crush who was 20 or so years older than them and the adult essentially grooming them.
exactly, tbh i have no problem when an adult meets someone whose way older than them and they develop feelings for each other. but when you've grown up with a child who doesn't know better than to mistake his feelings of admiration or validation for love, and you instantly forget about your parental feelings towards the child just because they began pursuing you is indeed very predatory
This childhood crushes on an adult Tropes or vice versa needs to die. It’s just plain weird and Moraless*
