It stars Jung Woo-sung and Son Ye-jin and follows the theme of discovery in a relationship and the burdens of loss caused by Alzheimer's disease.

One day while accompanying her father, who is the CEO of a construction firm, she coincidentally meets the man whom she earlier bumped into at the convenience store.

Though he initially appears like a rough and dirty construction worker, Chul-soo exudes sheer masculinity in its most basic physical form.

The second act follows the couple happily settling into married life, with Chul-soo designing their dream house and Su-jin learning to become a housewife.

As time passes, however, Su-jin begins to display forgetfulness, including an incident in which a fire breaks out because of a stove she'd forgotten to turn off.

On October 22, 2008, it was reported that CBS Films had secured the rights for an American remake, with Susannah Grant attached to write the screenplay.
