Last year, actor Lee Kwang Ki faced the most painful experience a parent could undergo -  his son, Suk Kyu, was diagnosed with swine flu and passed away last November. tvN's recent documentary Looking at the Stars reveals Lee Kwang Ki, a father having to deal with a piece of his heart being ripped out. On the documentary, he reveals a storybook that his son wrote and drew in the past. He sobbed, "Suk Kyu couldn't finish this storybook. After looking at it, I believe I will have to finish this for him. With this experience, I've thought about people who have a sadder life than that of our family. I will give all the money that I raise from selling this storybook to those people living difficult lives." While Lee Kwang Ki was recording the narrations for the storybook, he suddenly burst into tears at one point. The recording had to be stopped as everyone joined to comfort him, even crying with grieving father. His wife, Park Ji Young, started, "It's most painful to open my eyes each morning. It feels like my baby has died inside of me. If only I had been faster...." and was unable to finish her sentence, overcome with tears.
