Shige, a stout middle-aged man who took pride in his police uniform and looked down on security guards. However, due to the revenge of Nao, the security guard he insulted, their positions are reversed overnight. When he wakes up, he is wearing a reflective vest and a helmet. His police ID, his name, his salary, his home, and even his very life as "Shigeharu Ayashiro" have all become Nao's.

His former colleagues laugh and say, "You're a security guard, aren't you?" He is yelled at at an unfamiliar construction site, and when he returns to what was his home, Nao is there, stout-bodied and confidently wearing the police uniform. As Shige pleads, "I'm the real one," Nao laughs while adjusting his uniform collar. "What are you talking about, Shige? You're a security guard, right?"

Uniform, title, name, money, a place to belong. A middle-aged man is stripped of everything he took pride in and thrown into the job he once despised. Eventually, the once-arrogant Shige has no choice but to cry and cling to Nao, the only person in the world who knows the truth.

But what Nao wants isn't an apology or his old life back. It's to make the miserable Shige dependent only on him after taking everything, keeping him as a lover. From "Police Officer and Security Guard" to "The Taker and the Taken"—a dark BL of reversal and obsession where uniforms and status are flipped.
