Mu Xiaomu

Biodata

Background / History

Mu Xiaomu first appears at the company parking garage, where she apologizes after colliding with Lin Su. She is introduced to him as an Omega, prompting Lin Su to assume she is the female lead from the novel he knows. 8

Although she was placed beside Gu Lin through Old Master Gu, Mu Xiaomu does not pursue Gu Lin herself. Instead, she covertly works to bring Gu Lin and Lin Su together, treating their relationship as the “Shuang-Lin CP.” After finding Gu Lin absent from his room on the banquet night, she went to the floor where Gu Lin and Lin Su were together, left only after seeing their door close, and appeared relieved. 12 18 47

Her current personality differs sharply from the timid, weak woman Old Master Gu had bought off two months earlier. Gu Lin's investigation raises the possibility that Mu Xiaomu has become “a different person,” while she privately attributes the world’s altered circumstances to her own arrival as a “butterfly effect.” 30 47

Personality

Mu Xiaomu is an enthusiastic and unusually proactive shipper. She takes joy in Gu Lin and Lin Su's embarrassing or intimate moments, actively engineers encounters between them, and worries when their relationship stalls. 7 22 26

Behind a delicate, sweet presentation, she is bold, excitable, and calculating. She can perform the role of a harmless Omega when useful, but privately admits she is a Beta and deliberately concealed that fact. 8 30

She is also fiercely protective of her preferred pairing. Han Jin's familiarity with Lin Su immediately makes her suspicious; she regards him as an intruder trying to separate the couple. 19
