Seunghyun has Dara, Jiyong has Bom. Life feels like fairytale.

But what happens when one day they feel tired and need new experience?

"So you're saying, that we should exchange each other's girlfriend?" Jiyong looked at his hyung with confuse.

"Yeah. I mean, don't you feel bored with us? I mean, we've been living like this since high school..." TOP shrugged.

"Yah, you guys sure you can handle the situation?" Bom sipped her carrot juice while playing with her hair.

"I'm in." Dara leaned on Jiyong's back. "Why not? This is a new experience. Of course if you sure you wouldn't get jealous, Seunghyunnie~"

"Fine then. Let's do this until anyone of us decides to give up." TOP grinned. "You guys in?"

All of them nodded in unison.

Let the game begin!
