He specifically requests to share a dormitory with his suspected target, "Xu Wenjin." That night, Fu Jingxiu sneaks into the room to search. While frisking Chu Wanqing, who is disguised as a man and has taken Xu Wenjin's place, he becomes suspicious due to her slender waist. Startled awake, Chu Wanqing confronts him with a knife, bluffing her way out by claiming to be the "Prefect's son." The next day, Fu Jingxiu officially becomes her classmate. Using Chu Wanqing's earlier false claim of being attracted to men as leverage, he retaliates, forcing her to share a bed with him, pushing Chu Wanqing into a crisis of her identity being exposed.
