Can you call it grooming in romance stories, where they met when the mc is an Adult and the guy theyre supposed to be in a relationship later on in the story was a child.. and they watched him grow up? like basically raising him and shit but later on develops feelings for him when he's a full grown adult? does that make sense like..
