Lin Xiaoman, a frustrated office worker, gets dumped by her cheating boyfriend and fired on her birthday—only to bind with a "Sister Happiness System" that requires her to help her otaku sister Lin Xiaotang (obsessed with xianxia novels and never dated) find happiness to unlock her own luck. Forced to become her sister's "happiness coach," Xiaoman helps Xiaotang revamp her image and find a job, while dealing with hilarious system tasks: competing with a hanfu designer heartthrob for limited-edition hanfu, getting drunk while covering for Xiaotang, and even taking her sister to the mountain at midnight to "experience xianxia vibes." Along the way, Xiaotang stumbles into a hanfu shop and meets her Mr. Right, while Xiaoman reunites with her high school crush—now a startup boss. Through all the chaotic yet heartwarming mishaps, the sisters learn that happiness isn't from a system, but from supporting each other. In the end, both find sweet love and career success, proving that sisterhood is the best luck of all.
