· Shen Xi (28 years old): Chief analyst of Lujiazui Financial Company. She is a crystal rose in the glass curtain wall, precise and dazzling. Her life is defined by data and rules, but there is an unilluminated island in her heart.
· Chen Mo (29 years old): Shanghai's top food delivery rider, codenamed "Huangpu Eagle". He knows every capillary in the city, is efficient, silent, and carries mysteries and scars that are inconsistent with this job. His true identity will be the key suspense driving the story.
· Key supporting roles: Shen Xi's exquisitely egoistic best friend and snobbish mother; the simple and enthusiastic brother at the takeaway station; and a "mysterious client" who is closely related to Chen Mo's past throughout.
