That's the thing. Nobody talks about them, nobody should see them together, and nobody attempted to make them lie even to the camera (seeing that they are JE dudes and idols and all). I won't be convinced of anything other than intentional conspiracy. I used to think that "oh, they are just good friends wth" then you see so much of those "evidences" popping out and you can't help wondering if they were covered up for a reason.
