So first tao says t.a.o is what he wants to say from the bottom of his heart and in the song he says " you love me for who I am" and since he admitted he is gay in three interviews I really don't know what to say. 

Then in one heart he says the words wufan, yifan and kris.

And they wear the same headsets in china and then kris posts an image of tao in the yellow sweater in another angle that tao had posted on his weibo.

I mean seriously marry already YAHHHH MARRY PUFF ^^

Oh and they both say zifan in their mvs.

He says he is in you're my sunshine interview where they ask him about his character and he says he likes it because they are both gays. 

And in z.tao interview he says it was awkward working with the model because he isn't in to girls. And the third one I don't know. I just heard.
