"Why can't my older brother, despite being the crown prince, get engaged? I, his younger sister, know the reason, but your analysis is insufficient. My older brother... with Father and Mother like that, it's impossible."

"Why can't I get engaged even though I'm 18 now?!" my older brother shouts upon turning 18 this year. I know the reason why, but it's so typical of my older brother not to have noticed until now. Even I, his younger sister, came to understand it at age five. It's because of that major scandal from twenty years ago—the broken engagement and condemnation, dear brother. I've decided to explain the situation to my naturally airheaded older brother in a way he can understand.
