“Every man has his secret sorrows which the world knows not; and often times we call a man cold when he is only sad.” 

Kris Wu, Kevin Wu, Wu Yifan or Li Jiaheng. Whatever you want to call him, he was referred to as the 'Ice Prince' by every one in their school for he was as cold as ice. It was rumored that he shows no emotion, he was hard to read and that he cares for no one but himself. When a brave soul would try to talk to him, he would just walk away as if he never hear anything.

It went on like that for 18 years. One day, he didn't show up for school. No, it wasn't just a day. It was months! And before they knew it, they received a police report that said he disappeared and left no trace whatsoever.

Huang Zitao or Tao as his friends would call him. He was shy, friendly and he was also the school's country's wushu champion. He had a lot of friends even though he was shy and he blames it all on his roommate, Lu Han, who was such a social butterfly. One day, he was intrigued by a tall male who was rumored to be the 'Ice Prince' in their vicinity. Tao found his mysteriousness quite alluring and the next thing he knew, he was falling for him, the so-called ice prince.

Tao was heartbroken when he heard of the news, but he was persistent in wanting to find Kris and he dragged all his friends into the case as well. It wasn't long before they found themselves unravelling the secret past of Kris that lead him to be such a cold person he is today.

With the clues they found, will they be able to find Kris? What is really the history of Kris and why did he disappear? Does Zhang Yixing know something about Kris's past?
