Unexpected Love Presents...EXCHANGING BIASES

What if you got a bias exchange with your friend? JJ and Ali: best of friends, two fangirls of SuperJunior with biases Siwon (for JJ) and Kyuhyun (for Ali), both tourist guides. Then one day, their biases went to the Philippines for a secret vacation, only to find out that they'll be missing their chance because they'll travel not with their bias. Will their love for them be in jeopardy after the tour? Will their friendship be at risk if something happened during their separate tours?
This is a fan fiction for SuperJunior's Choi Siwon and Cho Kyuhyun. FYI: This is not Bromance XD
