Hae-Gon, Joon-Hyung and Hak-Rak are everyday guys, working at a local taxi company. Men of marked individuality, many wonder how they keep company with each other. After a bulky day of work, one and only diversion they can share is drinking in a local bar with silly jokes. Discontented with their miserable life, they finally decide to do something big, which they believe this is very and last opportunity to take an abrupt turn of their life. However, their plan makes a wrong turn, just like their pathetic life.

In the year 1999, a young woman leaves her quaint seaside house and returns to the city, leaving in the mailbox a card for the next owner, with instructions to forward any mail of hers to the new address. In the year 1997, a jaded young architect moves into the same house--and finds the letter. His reply, which he slips into the mailbox, finds its way to her, beginning a parallel-time love story separated by a span of two years.

Seon-woo receives calla every morning and wants to find out who the secret admirer is. One day, he goes to a nearby florist's where he meets Ji-hee. He falls in love with her at first sight, thinking she is the one who is sending him flowers. Seon-woo asks Ji-hee to go on a date and she agrees. He arrives at the rendenvous only to find that Ji-hee is held hostage and, to his horror, killed before his eyes.
