As a child, Ha-Myeong (Lee Jong-Suk) grew up in a family with his firefighter father, mother and older brother. Ha-Myeong and his older brother (Yoon Gyun-Sang) both possess higher than normal intellect and are proud of their father. A fire at a waste facility though destroys his family. His mother dies a short time later and Ha-Myeong ends up being scooped out of the ocean by an unknown man (Byun Hee-Bong).  The man that pulls Ha-Myeong out of the ocean is the grandfather of In-Ha (Park Shin-Hye). In-Ha's grandfather believes Ha-Myeong is his eldest son Dal-Po, who died 30 years ago. Ha-Myeong is then adopted by In-Ha's grandfather and his name is changed to Dal-Po. In-Ha and Dal-Po now live together as uncle and niece, although they are in the same age range. In-Ha has a Pinocchio Syndrome. Whenever she lies she gets the hiccups. In-Ha and Dal-Po get along well until Dal-Po learns that In-Ha's mother (Jin Kyung) is the reporter that covered the waste facility fire that destroyed his family. Dal-Po tries to distance himself from In-Ha, but he also develops feelings for her.  Years later, Dal-Po and In-Ha's family are now living in Seoul. In-Ha attempts to become a reporter like her mother. In-Ha meets her mother for the first time in years at a job interview for MSC Broadcasting Station. Her mother is the person giving her the job interview. In-Ha though fails the job interview. Her mother rejects her because of her Pinocchio Syndrome.  Dal-Po is now driving a taxi to support their family. One day, Dal-Po meets In-Ha's mother and decides to become a reporter.
