Plot Summary:They don't know when to stop, and live life to the fullest meet the never-a-dull-moment Sakurai family, where nobody holds their feelings back. Returning to serial drama for the first time in five years, Misako Tanaka and the three hyperactive sons provide a story with a heartbeat. Sakurai Harue (Tanaka) who has brought up her sons alone after her husband died, is absolutely hopeless at running a household. Her eldest, stickler Tatsuya (Tamayama), does the job in her place while keeping younger brothers Riku (Hayami), and Junpei (Nakao) firmly in line. The sparks are constantly flying, but that's the way it goes in this home. Tatsuya, a serious-minded advertising agency worker, and his brothers, an easy-going swimming instructor and rather naive student, are three good-lookers who, along with their useless live-wire of a mother, keep getting into all sorts of scrapes in love and at work. This is the Sakurai household, where everything hangs loose and everyone always speaks their mind....
