“without you, what is life? what is there to live for?”

Lee Jihyun and Zhang Yixing were planning to get married, Yixing however had business to attend overseas - in China.

“he promised he would be back.”

When the news of Yixing's death struck Jihyun, she was broken. However, she had to stay strong and carry on for their company. The ZhangLee Industries.

Lu Han had been there the night Yixing's death occurred. And Lu Han regrets it to this day. He regrets that he couldn't save the man who had greeted him so kindly that night.

To pay his respects, Lu Han visits Korea and finds out that Yixing had a fianceè.

The ZhangLee industries, which had once been one of the biggest and most respected companies in Korea was slowly being defeated and it was nearly going bankrupt.

Lu Han feels the need to save the company - out of guilt. The guilt soon turns into love.

But... Can Jihyun learn to love again? And love the man who had witnessed her fianceé's death?
