Going to complain about something. There's a common trope where a heroine fell in love with MC when they children, then meets him again but doesn't know he's the same person. This isn't bad in itself, but it is when it's treated as a central point of drama for their romantic development. Or more specifically, if her realizing that MC is the same person is what allows the romance to be fulfilled. What that means, I think, is that the heroine doesn't actually love MC as he is, because she isn't willing to be in a relationship with him until she knows he's the person she was already in love with when she was a child. Whenever I feel like this is going to happen in a game it makes me dislike the heroine because I know she's ultimately just hung up on someone else. The MC in front of her isn't that person, he's grown and changed over the years, and she won't date him unless he ends up being the person from the past, regardless of what else happens. It's a very hateful personality trait.
