When I said "need to be protected" I meant in a sisterly way (from my perspective) since I don't see them in a "romantic" light so to speak. I'll never be making a male file since I have no desire to marry girls, therefore I treat Elise and Sakura as if they were my own little sisters. I'm aware that Leon and Takumi are pretty young themselves, but being attracted to those characters it's not like I would care anyways since they're obviously ok with your character marrying them.
And as I sated as well, it's the same way if you're a guy and planning to marry Sakura or Elise, there is nothing wrong with that at all and people screaming about it being so wrong are just ridiculous tbh.
