I definitely would love a Tanabe route...
I saw someone mention how they think he only cares about Yuu because he's getting skillful again, but I read it as him being upset that Yuu gave up like he did after losing so many times. He admitted to not being good with people, and I can totally relate to that. I also had this thought in Keisuke's route that maybe Tanabe put distance between himself and Yuu because Tanabe realized he had deeper feelings for Yuu and was freaked out by it.
