An elderly Japanese man named Fujii came to Taiwan just to have a cup of coffee from his memory. Fujii is the grandfather of a Japanese barista named Natsuyuki. That year, Natsuyuki came to Taiwan to attend a coffee sharing event with Taiwanese barista Wang Ce. However, Natsuyuki's purpose for this trip was to fulfill his grandfather's wish. Fujii hoped to find the Taiwanese girl he had a crush on when he was young, and have a cup of coffee made by her again.
