I Raised a Sickly, Corrupted Boy

(Written on 7/5) The sickly, darkening prince of a neighboring kingdom × the sweet, charming princess adored by all. Both are pure, 1v1. The little princess of Beizhu Kingdom finds an unconscious boy. The boy is sickly and obsessive, yet blessed with a strikingly handsome face. Every time the little princess meets his gaze, she blushes. Before his fall into darkness, Yan Yu was merely a quiet, taciturn boy. “Ah Yu, why are you so handsome?” “Your Highness, no one can compare to your beauty.” “Ah Yu, it’s snowing. Would you make a snowman for me?” “I would be honored to serve you, Your Highness.” “Ah Yu, I’m going to choose a consort.” “Your Highness is peerlessly elegant. Your consort will surely be a remarkable man of his age.” After his fall into darkness, Yan Yu became obsessive and infatuated. “Ah Yu, would you give yourself to me?” “Your Highness, I’d be afraid I wasn’t quick enough.” [Content warnings: 1. The male lead is reborn. The female lead’s only role throughout is to be beautiful. In his previous life, the male lead had a beloved woman, who was the female lead, though he didn’t know it. 2. The male lead is polite on the surface but actually a lunatic. He uses the female lead in the early part of the story. 3. I’ll post a notice in the comments if I need to take a break.]
