Xiao Xu

Biodata

Background / History

Xiao Xu shares a mixed-major four-person dormitory with Duan Xu, Zhou Zhou, and later Shen Yanlang. He studies at the School of Physical Education and initially describes their arrangement as a “mixed bag” because all four roommates have different majors 2.

He joins the Cycling Club alongside his roommates, making its rides and outings a regular dorm activity 4. He also maintains daily training, reflecting his commitment to athletics 6.

Following university, Xiao Xu opens his own gym in a mall opposite Summit Technology, allowing him to remain close to his former roommates and the wider friend group as they begin their professional lives 104.

Appearance

Xiao Xu is a broad, muscular young man with ruggedly handsome features and a rough voice. His build remains conspicuous even in loose black sportswear, giving him the impression of a sunny, tough athlete 2 11.

• Rugged, handsome facial features 11
• Rough voice 2

Personality

Xiao Xu is deeply loyal to his friends and especially protective of Zhou Zhou and Duan Xu. He places himself in front of Zhou Zhou during Wei Xiaoyang’s intrusion and later attempts to prevent Shen Yanlang’s anger from becoming fatal, despite recognizing that Shen is far stronger than him 92 93.
