Dok Mi is a young woman with a comfortable routine – every morning, she wakes up and spies on her good-looking neighbor, Tae Joon, from her window and voyeuristically copies his morning routine. Unable to face people, Dok Mi works as a freelance copy editor with as little interaction with the outside world as possible. But her comfortable, predictable existence comes to a halt when her peeping is discovered by Enrique, Tae Joon’s younger brother who returns from a year in Spain and moves in with him. Suddenly, Dok Mi finds herself surrounded by a menagerie of young, good-looking neighbors who will not let her live her life in solitude. Jin Rak, a web comic writer who lives next door with his drawing partner, Dong Hoon, is intrigued by Dok Mi and develops a new web series about her. Watanabe, an aspiring chef, also moves in on the same floor. Will these pretty boys allow Dok Mi to return to her reclusive lifestyle or will they force her to come out of her shell?
