time together, Sam-soon and Jin-heon grow closer and gradually fall for each other. But just when things are going well, Jin-heon's ex-girlfriend Yoo Hee-jin (Jung Ryeo-won) returns from the United States. 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.

Sam-soon goes once again to the city clerk's office to have her name changed, but finally believing that her name is special and an important part of her identity, changes her mind at the last minute and tears up the papers. Two months pass, with no calls or letters from Jin-heon, and Sam-soon has given up on him and gone on with her life. When Jin-heon eventually returns to Korea, she gives him the cold shoulder. But the misunderstanding is cleared up when two months' worth of postcards gets delivered to Sam-soon's house; as they had
