Oh Song Kyung is a well organized 28-year-old bank teller. She meticulously has a plan for everything, including getting married through a dating agency. Taekwondo master Kang Dong Joo's biggest pleasure is buying lottery tickets in hopes of one day hitting the jackpot. He is forced to register with a dating agency because of pressure from his sister-in-law who wants to kick him out of their house. A few days after registering with the agency, they meet at a hospital where they have both been diagnosed with brain cancer and given just three months to live. With time running out, together they prepare for the last ceremonies of their lives: their funeral, by shopping for coffins, urns and burial clothes and chambers, as well as wedding plans.
