YMMV / Shomin Sample

• Audience-Alienating Premise: The entire plot is a group of aristocrats kidnap someone of lower caste to serve as a sole male student at an all-girls' school and threaten to execute or castrate him if their preconceived notion that he's homosexual turns out to be wrong.
• Base-Breaking Character: Miyuki could seem unbearable since she's an outwardly-stoic Kuudure, assuming you don't view her comments against Kimito as comedic.
• The Scrappy: Eri is nigh-universally disliked (or worse), due to a one-time selling out Kimito at the start of the series, and for her personality, despite not having appeared often/done much else, unless you count her in-universe voice acting roles. This was much to the surprise/dismay of the author.
• Shocking Moments: People were shocked when they realized that the Kimito-hating Miyuki Kujou had actually been kissing him awake every morning.
• Spiritual Successor: Many consider Shomin Sample to be a successor to Ouran High School Host Club due to their similar premise (an Only Sane Man commoner attends a super elite school and interacts with a harem of Sheltered Aristocrats).
