Male protagonist, the Third Prince and the emperor's favorite son. Tall, broad-shouldered, with a narrow waist and strikingly handsome features. His bearing is cold and distant. He is known for his composure and dislikes physical contact and perfumes. Despite this, he finds himself unusually drawn to Si Nan, allowing her to cling to him and even carrying her gently. He has a complex history with Si Nan, having been told by her as a child that he was handsome and asking him to be his wife, though Si Nan later treated him as an enemy. He had a major argument with the Emperor and was slapped by him. He serves as the primary authority figure confronting Si Nan and her friends after the treasury fire.
