@N0b0dy07 I wouldn't call 18 year olds "adult-minded" but that's nitpicky so I won't press it. But so, even if their minds were fully adult when they reincarnated, that's still 5 years of abuse and neglect. They can't get a proper read on their father, who keeps switching between drawing them close and pushing them away. As the audience, we know why, but the twins sure as heck don't. The brothers, even if they aren't complicit in the abuse, don't have the power to protect them from the emperor. Not to mention
trauma affects how people think, behave, and react
I don't really think the reincarnation thing is particularly necessary either, it's just an excuse to have them behave more maturely than the average 5 year old. Keyword being "more", since 5 year olds are
even worse at being reasonable or regulating their emotions. But they could just be mature for their age and nothing would change
