Chi Jian transmigrates into a book and becomes a prince, one of the cannon-fodder emperor candidates. After he steals Prince Fu, the protagonist's, study companion, Prince Fu's younger brother will raise an army and force his way into the palace a year after Chi Jian ascends the throne, dragging him off the Dragon Throne and castrating him.
After transmigrating, Chi Jian feels a dull ache down there, so he pulls the beautiful palace maid beside him close and gives her a big smooch. Is the throne that uncomfortable to sit on, or are beautiful women not sweet enough? Some study companion? Not interested!
~~A year after smoothly ascending the throne, Prince Fu storms the imperial city and demands, "Your life or your throne?" Emperor Qiling, Chi Jian: "I... want both. And your study companion too, thanks." An emperor who tries hard to act like a cute straight guy, on the bottom X A study companion whose charm is impossible to resist, on top. 1v1, happy ending. An imaginary setting, no need to nitpick the history.
Theme: Being straight isn't something you can pretend to be just because you want to.
