A story of love between the son of a man who runs a ship-repair factory beset with financial troubles and the well-bred daughter of a national jewelry chain store owner.
A boy and a girl from highly different social backgrounds meet and fall in love, though not without obstacles.
In contrast to him, Nao (Haruka Ayase) is the daughter of a popular jewelry shop owner in a fashionable street in Yokohama.
She attends a prestigious exclusive women's college and grew up cheerful and blessed with affluent love.
From the moment Hiroto meets her, his closed mind slowly opens up to Nao, who is so innocent that she utters whatever she thinks.
