The seventh man stood up to tell the story f how he lost his best friend to a wave.
He told them about his best friend, K, during his childhood and how he was an amazing artist. However, he was often teased for having a speech impediment which made him sound retarded. This is why the seventh man saw himself as K's protector when he was younger.
On the day in which a typhoon was set to pass, the eye of the storm had reached his village. He told them about how he and K had gone out to the shore during the passing of the eye. Unfortunately, while they were out on the shore, he lost K to a wave and passed out. When he passed out, he could have sworn he saw K floating in the wave with his arm outstretched to him.
Three days later, he woke in the hospital. He struggled recovering from the shock of the event, however, he only ever recovered physically.
He, soon after, decided to move away because of his re-occurring nightmares. He would continue to have the same haunting dream, all he could feel was fear. After he moved away, the dreams stopped and he tried to live a normal life. Years later he received a box full of K's artwork. At fist, this haunted him, but as he kept inspecting the artworks every day, the fear went away.
He finally decided to re-visit the shore where he lost K... There, he was at peace again. He finally let go...
