The new junior in his department, Seiichiro Mibu, is hogging all the babes and the promotions, and worse, he's such a great guy, Sakurada can't even summon any jealousy.

But when Sakurada awakens in a love hotel, all tied up, it's Mibu who strolls through the door. He's got a shocking revelation and plans to ruin Sakurada's whole week with a marathon of kink play and revenge! What's Sakurada to do, especially once he begins to enjoy it?
