The play is adapted from the Japanese TV series "Summer Without Love". This is also the second time that Song Hye Kyo has collaborated with director Kim Kyu Tae and writer Noh Hee Kyung. The gambler Oh Shu (played by Jo In Sung) lives in a poker world full of money and desire, and lives a gorgeous life. Every night, he is with women and wine except playing poker. Due to an accident, he is in debt of billions of won, so he sets his sights on the rich girl Oh Young (played by Song Hye Kyo). As the only heir to a large enterprise, Oh Young is smart, beautiful, and seems to have everything, but she is lonely and cold in her heart. Unfortunately, she suffers from "tunnel vision disorder" that can vaguely see the center of the field of vision and cannot see the surroundings. For money, Oh Shu brings his close brother Zhencheng (played by Kim Bum) to Oh Young's home, pretending to be Oh Young's brother who he has not seen for more than 10 years. The cynical him finds that Oh Young is as lonely and sad as himself, and gradually develops feelings for her. And Oh Young is also moved by the warm words and actions of this brother's lies and the free charm, and slowly begins to open her heart to him. And in the end, when truth and lies collide, when all the beautiful things they have built are shattered, what kind of ending will the two face?
