Destiny-Like Love.

During their childhood, a little girl and a boy made a pledge to meet again. Now at the age of 45, the girl, Kasumi, is now a divorced mother of a son of high school age. She works as hard as she can at a laundry delivery shop for the wealthy, in order to make a living. Then one day, Kasumi encounters a young male designer, Yuri, who has attracted international attention. He is somehow far too familiar with her and pokes his nose into her affairs. Kasumi is initially wary, but she soon learns that he has a pure heart and starts to get drawn to him. These two people with different backgrounds fall in love. Why did Yuri appear before her? Could he be the boy from that time?
