"Post-rookie" refers to employees who do not expect to climb up in the workplace by doing their best. They live every day in a muddle-headed mentality. Zhong Yutang (played by Joanne Tseng) is the secretary of Tianxi Group. She works diligently, hoping to be promoted to the chief secretary of the group one day. Who knows that the newly appointed executive chairman is Ji Wenkai (played by Aaron Yan), a childhood playmate with whom she has a deep misunderstanding. What's worse is that Zhong Yutang's various behaviors made Ji Wenkai label her as a "post-rookie". Not only did she fail to get a promotion, but she was demoted. In fact, Ji Wenkai used the method of provocation, hoping to arouse Zhong Yutang's fighting spirit, and Zhong Yutang also hoped to prove her worth to Ji Wenkai through her own efforts. In the process, dazzling sparks collided between the two people.
