Sang Hyuk asked Yu Jin to see him downstairs, and told her that he was not asking her to forget Joon Sang. All he wanted was to keep her accompany. Yu Jin thanked him but refused his request as she could not do this to him...

Sang Hyuk told Zhen Yu that he wanted to go back to Yu Jin. Zhen Yu told Sang Hyuk that Joon Sang was his half-brother. In shock, Sang Hyuk ran out of the house. His mother fainted.

Mei Xi was returning to US. Joon Sang told her that he would be joining her soon.

Sang Hyuk went to Yu Jin's house. He told her that he wanted to go with her. After that, Sang Hyuk met Joon Sang at his office. Sang Hyuk told him that Yu Jin was leaving and asked Joon Sang to help him... Joon Sang said he could not tell Yu Jin to go back to Sang Hyuk... Sang Hyuk scolded Joon Sang for he has hurt his family deeply. Then, Joon Sang realized that Sang Hyuk found out the truth, and asked Sang Hyuk what he wanted. Sang Hyuk told him that he wanted things to go back to the time before Joon Sang appeared and he stormed out...

At home, Zhen Yu told Sang Hyuk that he owed Joon Sang too much. Sang Hyuk was not interested and insisted on going abroad with Yu Jin and marrying her.

Joon Sang was informed by the doctor that his condition was not completely curable, and even a successful operation might leave serious side-effects... After the hospital trip, Joon Sang returned to his office. Looking at the model of Yu Jin's dream house and realizing his sight was deteriorating, Joon Sang completed the sketches/blueprints of the house overnight...

Next day, Joon Sang told Yu Jin that he was leaving for US the following day. He asked her to go abroad to Sang Hyuk, as he would feel at ease with Sang Hyuk taking care of her. Yu Jin refused to meet his request...

In the evening, he drove her home, asking her not to see him off at the airport... reminding her to eat regularly, sleep well, promise to live well... and they should not see each other again... the memory at the seaside should be their last memory of each other... He went towards his car, Yu Jin pulled him by his jacket but eventually let go...

Before Joon Sang left for US, he asked Sang Hyuk to take care of  Yu Jin.... Then, Sang Hyuk found out that Joon Sang was going to US for operation and might not survive... He rushed to Yu Jin's home, and told Yu Jin that Joon Sang was not his brother and Joon Sang was leaving because he was sick and might be dying... They rushed to the airport, but could not find Joon Sang...
Yu Jin left to study in Paris. Sang Hyuk came and gave her an airticket to New York, to visit Joon Sang. She accepted the ticket from Sang Hyuk, but left it on the chair at the airport...

3 years later, spring time ...

Yu Jin returned from Paris. She returned to work in her old company. Her senior showed her a magazine with a picture of her dream mansion. Yu Jin decided to take a look...

Joon Sang was at the mansion, apparently blinded because of the operation on his brain. He was feeling his way around the house, knocked off a piece of the jigsaw puzzle, but could not picked it up...

Yu Jin went to the island where the mansion is...

Joon Sang was sitting outside the mansion, remembered Yu Jin told him the best home is their lover's heart... and thinking whether she would like this mansion...

Yu Jin walked through the woods... walked towards the mansion...

Joon Sang got into a car... left the mansion...

Yu Jin got into the empty mansion, looked around, and saw the puzzle with a piece missing. She picked up the piece on the ground, and fitted it back, remembering the last time she fitted the piece into the puzzle in Joon Sang's office...

Joon Sang came back, heard a noise and asked who was that...
Yu Jin turned around, with tears in her eyes...

Joon Sang asked again...
Yu Jin did not reply....

Joon Sang asked, "Yu Jin?"...
Yu Jin replied, "Joon Sang"...

They kissed and embraced...
