LSM,CEO of Sm entertainment, has given 2 villas to his biggest groups for the summer. In one villa will be Suju and snsd and in the other Shinee and f(x) ( f(x) is debuting so they are absent for the summer). Suju and snsd both have their crushes on eachother but the most known couple is Yoona and Donghae, but when jessica starts getting feelings for donghae will he return the love? At the same time, Donghae feels that he likes jessica but being with Yoona would look better , as Yoona is the face of snsd.
