Go Dok-mi (in Korean, literally "lonely beauty")(played by Park Shin-hye) is a shy, frugal freelance copy editor who refuses to leave her apartment or interact with people as much as possible. Every day, using a pair of binoculars, she steals peeks at her neighbor across the street, Han Tae-joon, as he goes through his daily morning routine. She had fallen in love with Tae-joon at first sight, after witnessing him pick up a puppy in a box and taking it home. When she looked out her window and saw him living in the apartment opposite hers, she thought of it as fate.
