Dan-ah bears the emotional burden of being widowed at a young age, and is unable to let go of the memory of her husband who died in a serious car accident.

She has several unpleasant encounters with Kang-suk, an unscrupulous businessman whose main aim in life is to defeat his opponents in the business arena.

The elder is Ha Soo-young (Jeon No-min), a mild, placid man who meets and falls in love with a girl several years his junior (Shin Da-eun).

The second brother, Ha Tae-young (Kim Sung-min), is impetuous and outspoken, and finds his match in a tomboyish policewoman (Maya).

As relationships develop and paths cross, the fates of the Ha and Lee families become closely intertwined.
