Li Changge
Seeing Mimi's close resemblance to her mother, Changge asks Sun to keep Mimi by her side. Sun grants her wish but remarked that Changge should be careful with gifts here, especially the ones with eyes and ears, implying that Mimi might be a mole.

Mimi is grateful to Changge and, in return, saves Changge's life from her high fever. However, upon discovering that Li Changge is a woman, she is extremely disappointed for thinking that she had found a dependable gentlemen. Changge calms her, promising that she will do anything she can to protect both of them among the Turks. After Changge successfully secures Sun's favor, their ranks are upgraded along with better accommodations, remuneration, and servants.

From then on, they live peacefully as husband and wife for several months in Sun's khaganate. While Changge is on her strategist duty, Mimi is responsible for taking care of Changge's health and doing the chores. She gradually becomes a mother-figure for Changge, even protective of her when she has her first period during a meeting with Sun and Mujin. Mimi often scolds Changge for neglecting her feminine side and overworking herself. On the contrary, Changge greatly admires Mimi's bravery to continue living on as a woman in such chaotic times. Mimi even urges Changge to escape Sun's khaganate several times, assuring her that she will help her disappear.

Little does Changge know, Mimi has been hiding a tragic past behind her care-free demeanor. Sun's warning turns out to be true: Mimi is a mole working for Jin Se in exchange for her brother's survival. She has been secretly reporting about Sun's support for Jiaodan's Khitan clan and tries to poison Yaluo, Changge's messenger. Changge is heartbroken when she finds out about Mimi's betrayal, demanding to know what causes her to sacrifice her life like that. Having been exposed, Mimi refuses Changge's offer to leave with her and committed suicide with Changge's poisoned dagger.

Mimi's death has taken a great toll on Changge as she considers her as the only female companion around her age. The two even imagined their lives together, dressing up and going out as two young ladies. After burying Mimi, the defeated and devastated lies openly on the ground, never returning to Sun's khaganate and is assumed missing.
