Qiao Yifei

Biodata

Background

Qiao Yifei is approaching her fourth year at Huaqing University when she meets Jiang Fan. Despite consistently ranking first in her major and participating in numerous research projects with her uncle, she lacks enough academic credits. Her upcoming internship leaves her concerned about finding time to earn the remainder 27 29.

Appearance

• Build: Tall and curvaceous, with long, fair legs. In high heels, she stands almost as tall as the 183-centimeter Jiang Fan 27.
• Features: Curved willow-leaf brows, large phoenix eyes, a delicate nose, full lips, and a pointed chin 27.
• Hair: Long 49.
• Clothing: Introduced wearing a camisole beneath a sheer white gauze top, a short purple skirt, and high heels; later wears a miniskirt while watching the freshman challenge 27 49.

Personality

Confident and flirtatious, Yifei treats her reputation as Huaqing's campus belle as an advantage in persuading Jiang Fan. She initially mistakes his embarrassment for romantic interest, but becomes flustered herself when her staged fall brings them into close contact 27 28.

She is strongly motivated by academic rewards, particularly the credits needed for graduation. Nevertheless, she does not claim Jiang Fan's research insight as her own: when Qiao Shan asks how she devised the new measurement technique, she explicitly identifies Jiang Fan as its source 27 28 31.

Her banter with childhood friends is mischievous and physical, frequently turning into play-fighting. Although she privately rejects the idea of dating someone three years younger during her first outing with Jiang Fan, she later openly jokes about seeking handsome, talented freshmen at another university 28 49 50.

Abilities & Skills

Materials Science and Nanometrology

Yifei combines strong academic performance with practical research experience 29.

• Consistently ranks first in her materials science major 29.
• Participates in Qiao Shan's nanometrology project using atomic force microscopy 29.
• Relays Jiang Fan's explanation of nanoscale optical interferometry to Qiao Shan and helps develop the technique in the laboratory 30 31.
• Initially lacks familiarity with Jiang Fan's proposed methods and cannot independently confirm their validity before experimentation 29 30.

Flirtation and Persuasion

Yifei deliberately uses teasing, appearance, and staged vulnerability to influence Jiang Fan 27 28.

• Pretends to fall so that he will help her, then deliberately slips into his arms 28.
• Switches to discussing research when her physical flirting results in his prolonged nosebleed 29.
• Fails to secure his enrollment at Huaqing despite the eight-hour outing 30 50.

Relationships

• Qiao Shan — Her eldest uncle and research collaborator. He recruits her to help persuade Jiang Fan to attend Huaqing, offering to seek extra credits and a Special Contribution Award for her 27 28.
• Jiang Fan — Initially a recruitment target. His scientific advice earns her credits and a Research Innovation Award, leaving her grateful; she later watches his freshman challenge performance with renewed interest 29 50.
• Xiaoyu — A childhood friend associated with Dragon University of Science and Technology. They exchange teasing remarks and play-fight while watching its freshman challenge 49 50.
• Chu Ruoxi — Temporarily impersonates Yifei in messages to Jiang Fan after he mistakes her account for Yifei's. No direct meeting between the two women is shown in these events 34 36 47.

Story Role / Major Arcs

Huaqing Recruitment Attempt

• Qiao Shan arranges for Yifei to show Jiang Fan around Huaqing, hoping she can persuade him to enroll. Unknown to them, Jiang Fan accepts because his system offers a Stay-Up-Late Capsule for completing an eight-hour tour 27.
• Yifei repeatedly flirts with him around the campus lotus pond and on a bench. When his nosebleed will not stop, she takes him to the university infirmary for treatment 28 29.
• After lunch, she brings him to a book café to impress him with her academic knowledge. Instead, he calls her project's atomic force microscopy approach outdated and explains several optical interferometry methods 29.

Optical Interferometry Breakthrough

• After Jiang Fan leaves, Yifei reports his explanation to Qiao Shan, who immediately summons her to the nanotechnology laboratory 30.
• By the following morning, they successfully develop the technique. Its performance is several times better than their previous atomic force microscopy method 31.
• Although Jiang Fan ultimately declines Huaqing's guaranteed admission, his advice earns Yifei the credits she needs and Huaqing University's Research Innovation Award. This is distinct from the Special Contribution Award her uncle had offered to seek for recruiting him 28 50.

“Little Wildcat” Misunderstanding

• Jiang Fan mistakes the WeChat user Little Wildcat for Yifei; the account actually belongs to Chu Ruoxi, who continues the misunderstanding to investigate his feelings 34 36.
• Believing he is addressing Yifei, Jiang Fan tells the account to stop contacting him, names Chu Ruoxi as his girlfriend, and deletes the contact. These messages are not an actual conversation with Yifei 35 36.
• Chu Ruoxi later reveals the account's identity to Jiang Fan 47.

Freshman Challenge

• Yifei attends Dragon University of Science and Technology's freshman challenge with childhood friends, an event she visits annually to look for handsome, talented newcomers 49.
• A contestant's 56-second solution catches her attention; she recognizes him as Jiang Fan when the camera returns to him 49 50.
• Recalling his research advice and their outing, she watches him tackle the notoriously difficult third problem while her friends tease her about her interest in him 50.
