Today is A-Wei’s last day, but it’s her first day with Ching.

Nineteen-year-old Yi-Xin has been raising her younger brother Chen alone. One day, her father’s former mistress leaves a young girl named Xin-Fang in her care. As the days pass, the three begin to form a bond—one that is tender, fragile, and far more complicated than Yi-Xin expected.

Ah-Fu, burdened with overwhelming debt, moves into a container home deep in the woods with his nine-year-old son, Wei-Wei. Together with his girlfriend Jing-Wen and her seven-year-old daughter Huan-Huan, this makeshift, struggling family does their best to get through each day. Though life is poor, these small, fleeting moments gradually gather into a warm current of memories in the child’s heart. Years later, the container home they once lived in appears in the news. Wei-Wei is drawn back to those memories—Ah-Fu’s disappearance, Jing-Wen leaving without a word, a rusted biscuit tin, and a set of unclaimed human remains.
