Leo, a young Japanese college student, travels to Hawaii and eventually falls in love with Maria, an older Japanese-Caucasion woman.

When his boss, Dae Jung, goes missing in a ship accident, the company sends Woo Joo to Osaka to finish his business. On his last day in the city, Woo Joo chases someone looking exactly like Dae Jung to Taisho, an area in Osaka. He ends up losing him, but the sound of a guitar draws Woo Joo to a small bar, Pier 34. Its owner, Snow, somehow reminds him of Dae Jung, and listening to his music brings back memories. After passing out right there, Woo Joo ends up missing his flight back to Korea. He quits his job on a whim and soon meets Haruna, who is learning how to play the guitar from Snow. Woo Joo decides to stay at Pier 34 until he finds Dae Jung and so begins an unlikely vacation for him.
