"Yah! Im Yoona! Get back here!" The man's voice reverberated down the hallway of the building. Numerous other idols and their managers ran past as they hurried to get to the next studio for stage appearances, but also noticing the man stare back at the disappearing sight of the woman he had just yelled at to come back. However, it wasn’t anything new. You saw these messy break ups everyday in behind the scenes places like here, where the press couldn’t catch glimpses of idols' private lives and their underground relationships.

That man was Taecyeon. Ok Taecyeon, rapper of South Korean idol group, 2PM. He was a considered a saint amongst the thousands of celebrities. 

And that girl was Yoona. Im Yoona, face of the national girl group, Girls' Generation. 

And he was her boyfriend.

Make that her ex.
