Jonghyun and Key have been in love with each other for three years. They live with each other and do everything together.

Key's job was being a fashion designer, while Jonghyun's job was being a singer. 

Because he was a singer, he had to travel everywhere to do concerts, and Key understood that. He was fullfilling his life long dream and was proud of him. At least they still  talked to each other every night on the phone when he was gone, but was still quite sad that he was still so far away.

One day, when Key came back from work, he the TV to watch the news and found out a fire had started at a concert hall in Japan, just where Jonghyun was.

Key had called him, but he never answered.

Does Key have to face the fact that Jonghyun was forever gone?
