The promise made that day remains in Taiwan

My grandfather, who passed away when I was young, was a teacher in pre-war Taiwan. Using old photographs and sketchbooks I found among his belongings as clues, I embarked on a solo journey to Taiwan. There, I met the grandson of my grandfather's best friend, who had also taught at the same school. As we retraced the places and memories of our grandfather's time, our relationship gradually grew closer. A love story set in Taiwan, connecting the past and present.
