恬静舒适的海滨医院，有一个名叫佐佐木正平（竹中直人 饰）的医生。他貌不惊人，个子矮小，生活中散漫不羁，除了时常摸女护士的屁股外，在外还和酒馆老板娘以及女高中生纠缠不清。不过，就是这样一个似乎有些猥亵的人，心中却藏着一份纯洁无瑕的初恋。

Shohei works as a doctor in a seaside hospital. One day, a new patient is admitted to the hospital with ovarian cancer. Shohei is surprised to recognize Michiko, his first love from high school. Shohei has been leading a dissolute bachelor life, paying for the company of high school girls and dating an older woman who works in a local bar, but in reality, for the last twenty years, he has not forgotten Michiko. Unfortunately though, Michiko doesn't remember him at all. Shohei becomes more and more persistent in his attempts to get her to recall their past. At first she is annoyed by his overtures, but gradually warms to the doctor. Under Shohei's kind and patient care, Michiko's condition improves and her cancer becomes operable. The operation is a success, but now Shohei himself learns that he has terminal cancer.
