Since their first meeting he was harsh on her but later Kim Jong Kook has found out that she possessed many unique qualities which he respected. When he finally understood that his little donsaeng is his soul mate something terrible has happened to them. As a result he’s lost a big part of his memory and she’s disappeared from his life. Although he couldn’t remember her, he subconsciously knew about a mysterious big hole in his heart.

Initially she thought he was unfriendly and dangerous like everything in that new, foreign world. But somehow she was fascinated by him.  Sometimes she saw him in her dreams as a tiger. Maybe that’s why she started calling him in mind: “Horagi-oppa”.  She even discovered that he has a passion for art just like her. More and more she could see their inner similarity. That’s why she decided to overcome his stubbornness and perform a miracle – became his best friend. Finally, it worked but after a horrible accident she had to go from his life for his sake.

He remained in Korea and became a famous musician. She returned to the US and devoted herself to the visual arts. But the providence did not give up and did everything for these two people to meet again.

But what if Kim Jong Kook and Kim Sook Yin have become completely different people than before? Is it possible to recover the past, when old scars still manifest themselves? What really happened eighteen years ago? Whether their relationship can evolve into a completely new form?
