Intro. Jiyong and Harin's families were very close friends; Jiyong's mother and Harin's father were particularly close friends and wanted their children to grow up together and marry, which is exactly what happened. Jiyong and Harin grew up together and were now 18 years old. Harin was involved in figure skating, while Jiyong was a trainee at YG Entertainment. However, Jiyong's childhood hadn't been easy; he had suffered from many illnesses, which still caused him frequent seizures and attacks. Sadly, Harin had witnessed many of these since childhood and still does.
