Hee-jin had suddenly left Korea years ago, right after a car accident that had killed Jin-heon's older brother, his sister-in-law and a motorcyclist, and left Jin-heon (who was driving) seriously injured. Though Jin-heon's leg eventually recovered, emotional scars remained, a mixture of sorrow, guilt, and anger at Hee-jin's abandonment. But what he didn't know was that Hee-jin had been diagnosed at the time with stomach cancer, and she'd broken up with him because she didn't want to add to the tragedy he was already experiencing. Now in remission, she returns to Korea to ask for a second chance, followed by her Korean-American doctor Henry Kim (Daniel Henney), who is in love with Hee-jin and eager to learn his roots. Upon learning the truth, Jin-heon reconciles with Hee-jin.
