And to top it off, now he's managed to get himself stuck in a sham marriage with Takeru!!! While breaking the news, Seishirou vows to put Takeru and Reo's wellbeing even above his own life, sham or not, but then Takeru pushes him down on the bed and demands a different sort of consolation prize for going along with this plan...
