Kyungsoo has gotten himself in a huge pile of trouble when he agreed to make the all-famous Kim Jongin fall for his whiny little sister, Jung soojung, or also known as Krystal...unfortuantly Kim jongin is nowhere near being intrested in Krystal or no, he's actually intrested in a rather a petite doe-eyed boy...What will kyungsoo do when he finds himself drawn to the Male, he can't possibly betray his sister, in order to be happy now..can he?
