Sang Hyuk returned to work... Yu Jin passed the ski field project to her senior...

Sang Hyuk took Yu Jin home for dinner. He told his parents that they plan to study abroad. Yu Jin was surprised initially, but did not object. When she got home, she was in tears... She told her mum that Sang Hyuk suggested going abroad to study. Her mum thought that it was a good idea. Then, Yu Jin asked whether it was possible not to get married. She felt like a wicked person as she could forget Joon Sang.

Because of this, she has ignored Sang Hyuk's feelings in the past, and how could she be married to him now?
Man Yeong decided to take a few days off and he went back to his old house. While fishing at the lake, he met an elderly man who claimed to have rescued a child called Joon Sang 20 years ago from that lake. Man Yeong was confused...

Sang Hyuk went to interview Mei Xi, and met his dad there. Sang Hyuk overheard Zhen Yu asked Mei Xi whether she knew Kang Joon Sang and whether he was her son. Mei Xi said her son was well and alive, and she did not know Joon Sang...

After the concert, Mei Xi fainted. Man Yeong piggybacked her back to the hotel. Man Yeong asked the doctor (who was a family friend) whether he was his mum's only son, and whether he grew up in US. The doctor answered, "Yes".

Confused, Man Yeong went drinking, suspecting that he was related to Joon Sang. Choi Lim found him at the pub. She wanted to accompany him. Man Yeong asked her about Joon Sang. He asked whether he could be related to Joon Sang, or could Joon Sang be his twin brother, or could he be Joon Sang? Choi Lim shouted at him for uttering nonsense in order to get Yu Jin back. She insisted that he was Lee Man Yeong, not Kang Joon Sang... Man Yeong strolled to Yu Jin's home. He saw Sang Hyuk leaving her apartment...

Mei Xi woke up. Man Yeong asked her whether she knew Kang Joon Sang. Mei Xi replied that she did not know that person.

Choi Lim asked Yu Jin to help Man Yeong, as she could not bear to see him in pain...

Sang Hyuk went to Yu Jin's office to pick her up, but found her leaving. He followed and found her meeting Man Yeong... Man Yeong was happy to see Yu Jin, but Yu Jin told him that she came to return the polaris necklace....

At the crossroad, the traffic light was out of order. While waiting, Man Yeong asked Yu Jin whether she would notice him if he did not look like Joon Sang... Yu Jin confirmed that... Man Yeong asked Yu Jin whether she wanted to go to the next traffic light. Yu Jin replied that she got lost once when she was young because she took another path... her path has been destined, and no one could change it... if she changed her route, she might be lost again. Then, she dashed across the road, leaving Man Yeong standing at the crossroad, with the polaris necklace...

When Yu Jin arrived home, she found Sang Hyuk waiting. Sang Hyuk asked whether she came back from the office and she did not deny. Sang Hyuk gave her a necklace as a present...

Next evening, Yu Jin's senior asked her for a drink while she was travelling in Sang Hyuk's car. She did not want to go. Sang Hyuk asked her whether Man Yeong was there, and she replied no. However, when Sang Hyuk and Yu Jin arrived at the pub, they found Man Yeong there. Man Yeong stood up to leave but Sang Hyuk told him that he could stay. Then, he left with Yu Jin. Outside the pub, Sang Hyuk asked Yu Jin why she lied to him. Yu Jin tried to explain but Sang Hyuk drove away...

Man Yeong found Yu Jin alone, hailing for taxi. Cars zoomed by, and he pulled her back from the road...
