Apparently there is this rumour about Sehun dating Taeyeon before Baekhyun dated her and Sehun and Baekhyun are on bad terms with each other [If you really believe this then you're a fool]

There are gifs and all about this issue.

As you can see here, Baekhyun slapped Sehun

And as you can see here, Sehun seems to be angry and he pushed Baekhyun's hand away

And Baekhyun grabbed Sehun really hard 

Sehun loves his hyungs so much that he even cried on the radio show, how could he have pushed Baekhyun's hand away? I think Baekhyun grabbing him and slapping him was just an accident. People are trying to bring Baekhyun down after the news of him dating was released. Please do not believe in any rumours unless its CONFIRMED. 

I know this story is called EXO Facts but I just wanted to post this to tell you guys that you shouldn't believe in any rumours unless its confirmed. The Baekhyun and Sehun fighting over Taeyeon is just a RUMOUR. If you believe it you're a fool.
