  FLASHBACK SUMMARY:
  

Jin's wife, Sun-Soo Kwon came to the island by accident, after nearly leaving her husband. Her marriage began with great promise, as Jin managed to convince her wealthy father, Mr. Paik, of his intentions. Unbeknownst to Sun, however, her strained relationship with her husband, stems from his employment to her unscrupulous father. When Jin came home one night with blood on his hands, Sun grew afraid of him and what kind of work he was doing for her father. Jin feels it would be dishonorable to tell Sun about her father's shady dealings and his silence before the crash led to the dissolution of their relationship. Sun began taking English lessons in secret. Finally, with the help of a friend, Sun was given a chance to escape her husband while at the Sydney airport. A single moment of tenderness from Jin while waiting in the check-in line reminded her of her love for him, and she decided not to leave him at the last minute.
