SNSD and EXO Pov:
When we were in the dressing/waiting room Taeyeon was the first one to notice that Yuri and Kris weren't with them. They became really worried about both of them. They were about to go look for them but when they were about to leave they saw a furious Yuri and a scared half piss Kris.
"Oh my gosh what did Kris you do this time" Taeyeon asked Kris that was still be dragged by Yuri
"Unnie he didn't do anything, it was Donghae that did everything" Yuri hissed and let go of Kris
"What did Hae oppa/hyung do" All of them asked at the same time with their eyes wide open 
"Aishh I don't wanna waste my ing time talking about the bastard" Yuri replied closing her eyes trying to calm her down
"Kris what did Donghae do" Kai asked all curious about the situation
So Kris told SNSD and EXO about what Donghae did to her and him when they were at the hospital
"Hyung noona what are you going to do about Donghae you guys should tell Leeteuk or the manger about this" Kai asked walking in circle trying to think of more plans
"Oh Kai boy that won't do" A stranger went to their door and smirked at all of them
"Yah Donghae what the to you think your doing messing around with Yuri and Kris" Kai screamed in anger
"Woah calm your balls down...wait you don't have non my bad" He walked out by laughing
"Aishh how are we going to stand him, and it's going to be really easy for Donghae to come fight with anyone of us" Kai started to mess his hair in anger
"Agioo Kai me and Kris are going to end this at one point, so for now all of you please ignore him so he won't do anything bad to you guys"Yuri smiled 
"SNSD your next to perform" The producer came into tell that they are next 
"SNSD Fighting!" Exo cheered them on before they went to perform
When they went on stage SNSD I got a boy was put on. That was the songs that they will be performing. SNSD I GOT A BOY LIVE When it was Yuri turn to sing the Exo members could see that Donghae was smirking at her everytime she was in front. He also laughed at her rap in the beginning with Sooyoung. When they saw that it got them really really mad that they want to go up and punch his handsome face.
