I like Takumi. He's an egotistical, calculating, cheating, lying, abusive, self-centered asshole but I believe his feelings for Nana are genuine, even if he doesn't fully understand or appreciate them yet. More importantly, I believe that Nana is the best thing that's ever happened to him in his life and he simply hasn't realized it. So despite all the horrible things Takumi has done I was still happy to see them together with their daughter in the future.
