Kim Jonghyun still remembers his best friend Jung Sooyeon from when they were little.  Bu then, Sooyeon's family moved because her dad is the owner of the billion-dollar-company Geo-sung.  Since then, things did not go so well for Jonghyun.  His mother becomes sick with cancer, his father is a drunk so Jonghyun always has to protect Taemin(little bother) from being abused,
