People say, "Its a small world.", but for two people, this quotation doesnt make sense. Two people, who are living on different horizons, share the least thought that most people talked about. For these two people, who base their lives on two quotations that they believe in, share and believe one quote in common:  "People come, people go. They will drift in and out of your life. Almost like characters in your favorite book. When you finally close the cover, the characters have told the story and you start again with another book - complete with new characters and adventures. Then, you find yourself focusing on the new ones, not the ones from the past."   Foreword Song Ji Hyo believes in the saying that blood is thicker than water, so when her one and only younger brother asked her to pretend to act as a person who is totally her opposite, she didnt hesitate to agree. She loves her brother so much more than her life and shes up to live her life making his younger brother happy all his life. Although they are poor, the love that she gets from her younger brother makes her the richest person in the world. Kim Jong Kook believes that a lie has a short life, but truth lives on forever. He hates to lie just to please someone else, and he hates people who lie just to please him. In this world, the only thing that he cares about is his famous younger sister. Just her, and no one else. He is known as a very righteous, yet a very ill-tempered and strict person. Because he was born rich, he makes sure that everything about him and his sister go well accordingly.  For these two people who have one quote in common, yet one quote in contrast, will it be possible for them to spread their wings, so the two of them could fly and soar high without being too attached in the past? Or, would they just continue to think that all good things in this world will never ever last?
