Aigan Ningyou to Kako ni Torawareta Kanojo

A young man begins receiving private lessons from a female home tutor, expecting nothing out of the ordinary. However, his routine visits to her apartment take an unsettling turn when he notices something peculiar within her living space. Among her belongings sits a strange mannequin, an object that immediately captures his attention and leaves him deeply unsettled. What disturbs him most is not merely the presence of the figure, but its uncanny appearance. As he studies it more closely, he realizes that the mannequin bears a striking resemblance to him. The likeness is far too precise to be dismissed as a simple coincidence, raising uncomfortable questions about why she possesses such an item and what it might signify. Unable to shake the eerie discovery, the young man finds himself consumed by curiosity and unease. He is left wondering about his tutor's true intentions and the hidden reasons behind keeping a doll modeled so perfectly after his own image. This mysterious encounter marks the beginning of a troubling enigma that threatens to unravel the boundaries between his everyday life and something far more inexplicable.
