A love story between Yang Kang-Cheol (Jung Woo-Sung) - an ex-prisoner who was incarcerated because of his friend's conspiracy - and a sensitive, yet guarded veterinarian, Jung Ji-Na (Han Ji-Min). They meet by chance and begin to fall in love with each other ...  Kang-Cheol and Gook-Soo (Kim Beom) leave prison on a furlough. Kang-Cheol has been in prison for 16 years. They have only one month left until their release. They are both given cellphones to take with them. When the phone rings they have to immediately answer where they are and what time it is. Both men are extremely excited to be on the outside. They get on a crowded subway and are pushed by other passengers. Kang-Cheol ends up in front of a woman. The woman's name is Ji-Na (Han Ji-Min) and she asks Kang-Cheol to give her some more space. Kang-Cheol can't move, though. When Ji-Na gets off the subway train she kicks Kang-Cheol and flips him the bird as the train departs. After Kang-Cheol and Gook-Soo get off the train they board a public transit bus. Gook-Soo asks Kang-Cheol to come and stay at his dad's house. Kang-Cheol doesn't like the idea and wants to meet a friend that was released from prison. Kang-Cheol saved his friend's life twice while in prison.  Kang-Cheol got off the bus without Gook-Soo knowing. Kang-Cheol then goes to a motel and has a good time alone. He then goes out to meet his friend from prison. On his way he spots a woman who looks familiar. Kang-Cheol then realizes the woman is the lady from the subway who kicked him.
