Twenty-six-year-old graphic designer Lin Ran joined the well-known advertising company "Imagination Media". Her immediate boss, creative director Liang Yan, was a cold-faced tyrant known throughout the company. On her first day of employment, she discovered that everyone in the company was secretly discussing how similar she looked to Liang Yan's ex-girlfriend who died unexpectedly. What shocked her even more was that her online dating partner "Xiao Yu", whom she had been chatting with for half a year and had mutual spiritual support for, turned out to be the other identity of her immediate boss. In reality, Liang Yan used a cold workplace mask to isolate everyone, but he confided all his vulnerability and tenderness to her. When the two identities completely overlap, Lin Ran must make a choice between keeping his job, preserving his self-esteem, and making mistakes.
