Hyunjin's your enemy. You guys hated each other ever since elementary school but your parents were best friends they always tried to make you and hyunjin get along but it never worked, so they decided to do whatever it takes to make you and hyunjin become friends (or a little more) so they set up a water park that you guys were staying in for a week. You thought it would've been fine until you had to share a room with hyunjin. That would've been bad but to make it worse there was only 1 bed.
