Takuro of Ronin begins to peep at Ichihana who has come to the next apartment. For Takuro, Ichihana has been a childhood friend and longing person since he was little, and Takuro could only peep from a distance because of his dark and withdrawal personality. As I peep every day, I feel like I want to get closer to her, and finally I step into a line that should not be crossed. I am prepared to be notified, but from that day I get on the temptation from her and have sex every day.
