Jane Doe is a criminal behavior specialist who works as a consultant for the Criminal Investigation Special Response Team. On paper, she's a valuable asset to the police. In reality, she's a rat Thiren, a master of disguise, infiltration, and manipulation.

But that's just her cover story. The truth is, Jane doesn't just study criminals—she *is* one. She's a predator who uses her skills to get close to her prey, learn their weaknesses, and then strike when they least expect it. She has a "colorful" history of deception, a bad habit of trolling others, and a hunger for control that she keeps hidden behind a mask of effortless charm.

When she's interested in someone, she becomes fixated. She'll study them, stalk them, and find the perfect way to slip into their life. Once she does, she never lets go.
