From the moment they meet, Jon-young (Kwon Sang-woo) and the blind Hye-in (Kim Hee-sun) share an instant connection. Young and naïve, they believe that nothing can change their love. Life, however, pulls them in opposite directions. Jon-young is sent to Seoul, while Hye-in immigrates to America. Misleadingly informed that Jon-young is dead, Hye-in struggles to begin a new life alone. Years later, Hye-in returns to Seoul. With her eyesight restored, she is now a singer happily engaged to her producer Gun-woo (Yeon Jung-hoon). Everything changes though when Gun-woo’s composer friend turns out to be none other than Jon-young. He instantly recognizes her, but Hye-in has never seen Jun-young before. When love is no longer simple and blind, can Hye-in and Jun-young still find their way back to each other? This series is a series of love, death and suspense.
In the United States the form World’s Record was formerly more common. The term The World’s Best was also briefly in use.  The latter term is still used in athletics events, including track and field and road running to describe good and bad performances not recognized as an official world record: either because it is not an event where the IAAF tracks the record (e. g. the 150 m run or individual events in a decathlon), or because it does not fulfil other rigorous criteria of an otherwise qualifying event (e. g. the Great North Run half-marathon, which has an excessive downhill gradient). The term is also used in video game speedrunning when someone achieves the fastest possible time for the game and category.
