3Shy Ichitaka has a crush on his high school classmate Iori, but ever since she posed for semi-provocative swimsuit photos in a magazine, she's had a lot of sleazy guys hitting on her. Ichitaka's afraid to make his feelings known for fear Iori will think he's just another creep.

Since it's summer vacation, classmate Teratani talks Ichitaka, Iori and some others into going to a seaside inn, ostensibly to study for college entrance exams, but really to hang on the beach. Still stinging from his most recent rejection by Iori, Ichitaka runs across a beautiful girl named Izumi, who seems determined to monopolize his time! Then an unfortunate incident in the hotel's hot spring puts him and the girls in the most embarrassing situation. Will he be able to regain Iori's trust, not to mention his own dignity?
