Shinya is working as a cook-in-training. One day, his mentor and employer Daigo told him that his old acquaintance Kyouko badly needed help at her restaurant since she was injured. Daigo sent him to save the restaurant Marine House Aqua and informed him that it would serve as the final test of his training. Shinya was elated that this moment of his dreams had finally arrived. He struggled in his new position, but the girls in the restaurant all try to help him out. His relationships with them grow closer and his summer love story has begun. (Source: Hau~ Omochikaeri!)
