bruh, if all you people want to do is complain, then don't come here to read this. The translators and the author didn't do this just so they could deal with your useless complaints. Also, just because they're mentally adults, doesn't mean they should know better. This is during the old society where nobles exist, and not to mention they haven't had a decent human contact or a good book to properly explain the world they're currently living in for the past five years. The fact that they were abused is also another thing to not look past.
