The eldest son of the Duke of Yu, serving in the Ministry of Justice. He appears stern and aloof, but shows deep care for his newborn son, often visiting the infant late at night despite his heavy workload. He respects his wife Wen Jingshu, yet maintains an emotionally distant courtesy. During a chance encounter when Liu Wenying is breastfeeding, he is momentarily caught off guard but quickly regains composure, later advising her to remain stable for the child’s sake. His sharp observation skills, honed from criminal investigation, allow him to notice subtle changes in others. He is a man of few words who values duty, but also displays a hint of hidden warmth.
