Background / History

Su Yuan grew up in a family whose fortunes declined after her father died in a car accident. During elementary through high school, she became a feared delinquent after using a brick to defeat an opponent; her mother, Su Caiwei, eventually persuaded her to reform before her final year of high school 17.

Before her transformation, Su Yuan played the fox-spirit character Little Fox in Zhu Xian 2. She favored flashy gameplay, acted cute to obtain equipment from wealthy players, and entered an in-game marriage with Ye Huang 2. She later learned that Ye Huang was her roommate Ji Yehao 141.

After buying a Jade Talisman Seal from a young Taoist priest, Su Yuan experienced a physical transformation and discovered that she had become female 2 6. She initially concealed this change, continued living in a male dormitory, and withdrew from high-profile opportunities such as the league branch secretary election 12 39. As her appearance became increasingly feminine, she began using the name Su Mengyuan publicly 110 127.

Su Yuan eventually accepted her female identity, moved out of the male dormitory, and became more open about dressing as a woman 85 106. Her later investigations connected her transformation, the jade, alien technology, the X/Y organelles, and the time-based ability known as [Rewind] 405 424.

Appearance

Su Yuan is repeatedly described as a striking, naturally beautiful young woman with a cool, elegant presence. Her appearance resembles Su Caiwei closely, and her feminine aura remains difficult to conceal even in neutral or masculine clothing 54 68.

• Slender build and graceful figure, though not especially tall 122.
• Clear skin, defined brows, bright eyes, and a cold or aloof gaze 122 256.
• Medium-short to shoulder-length dark hair as her appearance develops 161 256.
• Prefers practical, casual clothing and initially uses tracksuits, glasses, and sunglasses to obscure her figure and appearance 51.
• Her public image alternates between a cool beauty, “ice queen,” tomboy, and unexpectedly cute “Bun Girl” 84 204 206.

Personality

Su Yuan is resilient, proud, and highly adaptable. She endures her transformation in silence rather than expose her secret, while maintaining her studies and daily routine 39. She is practical with money, capable of bargaining, selling her game account for a higher price, and seeking tutoring work during financial hardship 14 51 56.

Her temperament combines a cool exterior with a fiery, mischievous streak. She dislikes arrogance, exploitation, and people who bully the weak, and she is willing to confront them directly—including Peng Jie, Tang Yue Lin, and multiple harassers 18 266 340. Her childhood as a delinquent left her fearless in confrontations, though she later tries to act with greater restraint 17 266.

Despite her sharp tongue and stubbornness, Su Yuan is loyal and generous toward friends. She advises Gao Jun, buys expensive clothes for Ji Yehao and Gao Jun, supports Tang Yue Lin despite their past hostility, and offers major financial help to a former classmate with leukemia 54 138 257 326.
