Kai, Chanyeol and Kris go on a vacation to a lovely beach and find out the next door neighbors are very cute. Luhan, Xiumin and D.O. all decided to bond on a vacation for three when they take a liking to the super hot guys next door. Suho manages a lovely condo unit on basically beachfront property, and can't seem to stop thinking about the sleepy delivery boy Lay. Sehun cleans the pools to make some summer money since his best friend Lay knows the manager somehow, and when the managers awfully good-looking younger brother Tao comes for a visit after travelling for school, Sehun finds himself wanting to be at work as often as possible. Chen and Baekhyun manage the best foodtruck in the tourist town, and happen to be twin brothers.
