Vijay Vs Vijay- Do they play friends-turned-enemies in Master?

The buzz about Master is getting bigger with each passing day. The film by Lokesh Kanagaraj has two of the most loved actors of Kollywood pitted against each other. It is rumored that Vijay plays the hero John Durairaj whereas Vijay Sethupathi plays the villain Bhavani. But, as per latest reports, the two were friends in the beginning and turned foes later due to certain incidents. A few lines in the recently released lyric video Polakatum Para Para hints that way. Also, Vijay Sethupathi said that he is not the real villain, but Vijay is the villain for his character and vice versa. Sure to have a childhood friendship connection or an interesting flashback.
