Song-ju is the only son of a wealthy family. Jung-suh is Song-ju’s childhood friend, and they were there for each other when one of their respective parents passed away. They spent a lot time together, playing, and sharing their inner most thoughts. When Jung-suh’s father re-married Tae Mira, Mira brought her children Tae-haw and Yuri from her previous marriage. That marked the end of Jung-suh’s happy days. Yuri was jealous of the privileged life that Jung-suh led, and vowed to take everything away from Jung-suh, including Song-ju. When Song-ju left for his studies in the U.S., he gave Jung-suh a necklace as a gift of his love.
