About the title
Con artist and master liar Yeon-ju is released from prison early. On her way to her sister's, she meets (in a rather odd way) Hee-chul on a train, who is heading to Seoul to propose to his girlfriend. Except a pickpocket steals his engagement ring. And Yeon-ju is the one who could be suspected of everything, which would send her back to prison. She jumps off at the station and grabs the ring back from the thief, but misses her train.
