Corporate secretary Shirotani suffers from obsessive-compulsive disorder. One day he meets Kurose, a therapist who offers to take him through a ten-step program to cure him of his compulsion. As the two go through each of the ten steps, Shirotani's attraction to his counselor grows.

At the mercy of Kurose's hands and words, Shirotani finally hears the full reason Kurose fell in love with him. The truth is such a surprise that Shirotani runs away from him in shock, and it isn't long before his body starts aching for Kurose's touch, causing Shirotani to soothe his own desire. But in doing so, he scares up memories of the traumatic event at the core of his compulsion.
