Bilibili describes the plot of the series as follows:
The weapon of choice in the entertainment industry is deception. Goro, an obstetrician and gynecologist in a small town, lives a life unrelated to the entertainment industry every day. However, the idol he "followed," Hoshino Ai, began to ascend up the list of stars. When these two recognized their worst-case scenario, the wheels of fate began to turn.
