Next day, on the way to school, Yu Jin was thinking of what she should say to Joon Sang about him missing their date. When she heard that Joon Sang was killed in a traffic accident, she could not accept it. By the lake, the classmates burnt paper offerings for Joon Sang, and Choi Lim accused Yu Jin for causing Joon Sang's death...

Back home, Yu Jin received a belated Christmas present from Joon Sang. It was a cassette tape containing "the first time", played and recorded by Joon Sang himself… She broke down and cried...

Ten years later, Yu Jin opened a renovation company called Polaris, while Sang Hyuk worked at the radio station. Zhen Suk was jobless and stayed with Yu Jin. Lung Kok became a veterian.

Polaris was involved in a ski field project with a company called Marcian. Yu Jin visited Marcian when they were moving into the new office premises. She picked up a piece of puzzle on her way out.

Later that evening, on the way to her engagement ceremony, Yu Jin saw a man who looks just like Joon Sang. Unconsciously, she followed him around, and forgot to attend her engagement ceremony. Everyone was waiting and Sang Hyuk's mum was very upset. Eventually, the exhausted Yu Jin turned up at the engagement venue but fainted in front of her family and friends...

The next day, Yu Jin went to Sang Hyuk's house to apologize but his mum was still upset. However, Sang Hyuk was very understanding, and did not even asked what happened. Yu Jin went home and listened to the tape left by Joon Sang 10 years ago. She started scribbling something on a piece of paper...

With the engagement ring, Sang Hyuk went to Yu Jin's home. Yu Jin was not around but Sang Hyuk saw her scribbled notes, saying that she has not forgotten Joon Sang and whether she was in a dream seeing him alive and walking on the road... Later, Sang Hyuk found Yu Jin in a park. He told her that she should have told him and he will wait with her...

Choi Lim sent an email to the old classmates, telling them she is back from France...

Lung Kok and Zhen Suk decided to help Sang Hyuk and Joon Yin to complete their engagement ceremony. Sang Hyuk drove Joon Yin back to the high school. At the courtyard, he put on the ring for her.... At the celebration party in the broadcast room, Choi Lim showed up and told everyone that she has opened a boutique. While they were talking, a man who looked exactly like Joon Sang showed up. Everyone was shocked when Choi Lim introduced him as Lee Man Yeong, her boyfriend.

Next day, Yu Jin went to Marcian. In the manager's office, she found a puzzle with a "hole", i.e., a missing piece. She removed the piece if puzzle she picked the other day from her pocket … fitted it in the "hole" … then, Lee Man Yeong appeared at the door, with the most brilliant smile...
