Miho and Takeru are finally getting used to living together. However, Takeru has noticed a difference in their feelings towards Miho, who has recently started coming home late at night and sporadically replying to his emails. He accidentally sees an invitation email from a man, and when Miho comes home late at night smelling of cigarettes without being able to contact him, Takeru explodes with jealousy. He forcefully pushes Miho down, carves love marks all over her body, and "punishes" her...!
