返家的航線上，海浪緩緩推著，主角想起小時候阿公摺的紙船。反覆回想著步驟，一條線、兩條線、一條跟著一條。船跡化為紙痕，隨著船隻駛進舊回憶，那裏有稻田、磚房、腳踏車和小路旁的溝渠。

《一》藉由回憶摺紙船的步驟傳達對於阿公的思念，描述返家途中的主角再次摺起阿公的紙船。紙上的摺痕交疊後匯集於中心點，如同河川最後匯集到大海一般，在這些翻轉紙面的過程裡，似乎漸漸了解阿公的人生哲理。

 Levi recalled the origami boat folding by his grandpa in his childhood when taking a boat on the way back home. "First step ; next step ; step by step..." he repeated the instruction of making the papership that taught by his grandpa.With the ocean waving slowly, the wake of a boat became a crease on the paper and brought Levi into memory.

"One after another" is a short film that depicts a grandfather-and-grandson relationship through the act of folding an origami boat. Once he folded paper and he found the creases on the paper overlapped and gathered at the center, just like all rivers eventually flow into the sea. In the process of turning over the paper, it seems that he gradually understands the philosophy of his grandpa.
