An Ha Yeong is having extremely bad luck. Her boyfriend of 99 days just broke up with her, ruining the chance for their 100th day anniversary -- an important milestone in any Korean relationship. In order to relieve her stress, she kicks a stray soda can with all of her might on the way home. The can happens to hit selfcentered college student Gang Hyeong Jun in the face while he's driving, causing him to crash into a nearby wall. Furious, Hyeong Jun demands Ha Yeong pay for the damages to his car, but she insists she doesn't have any money.
