When Amber has grown up and can live in her own way, she already has a great family with mom, dad and her lovely brother- Jonghyun.

When Jonghyun has grown up and is a shining star, he already has a great family with mom, dad and....the one he loves more than his own life. His heart is full with warmness and happiness when having a new happy family. But...there is still a dark and painful space in his heart, a space will never be soothed.

What happened to his life?
