Personally, I see people very giddy and alright with stories where the main characters are raised as siblings but they're not “real siblings” and not blood-related so it's fine if they're a couple. Besides it downplaying and seemingly insulting children who are adopted saying they're not “real family because they're not blood-related” it's also outright disgusting. For example: Beware of the brothers, the villainous sister of the grand Duke, the viridiscent crown etc. I personally cannot bear it. I despise the trope even. Especially because when you're raised as siblings, YOU ARE SIBLINGS . you call the same people parents and each other brother sister and it make some disgusted. Especially so with beware of the brothers, like Hari, if that's her name, was picked up by the Ernests (or whatever their name was) because she was the splitting image of their real daughter and Eugene's real sister and it's so disgusting to think he fell in love with his adopted sister who looks exactly like his dead sister and that made me drop the story the second I read that spoiler. Nonetheless, I will listen to all your opinions on this whether they be positive or negative because I'm curious as to what you guys think.
